Inputting Calculation Expressions and Values k Inputting a Calculation Expression Your calculator lets you input a calculation expression just as it is written and execute it by pressing w. The calculator determines the proper priority sequence for addition, subtraction, multiplication, division, functions and parentheses automatically. Example: 2 × (5 + 4) – 2 × (–3) = 2*(5+4)2*-3w E-7 2× ( 5+ 4 ) – 2× - 3 24 A Inputting Scientific Functions with Parentheses (sin, cos, ', etc.) Your calculator supports input of the scientific functions with parentheses shown below. Note that after you input the argument, you need to press ) to close the parentheses. –1 –1 –1 –1 –1 –1 sin(, cos(, tan(, sin (, cos (, tan (, sinh(, cosh(, tanh(, sinh (, cosh (, tanh (, log(, ln(, e^(, 10^(, '(, 3'(, Abs(, Pol(, Rec(, arg(, Conjg(, Not(, Neg(, Rnd(, ∫(, d/dx( Example: sin 30 = s30)w s i n ( 30 ) 05 A Omitting the Multiplication Sign You can omit the multiplication sign in the following cases. • Immediately before an open parenthesis: 2 × (5 + 4) • Immediately before a scientific function with parentheses: 2 × sin(30), 2 × '(3) • Before a prefix symbol (excluding the minus sign): 2 × h123 • Before a variable name, constant, or random number: 20 × A, 2 × π Important! If you execute a calculation that includes both division and multiplication operations in which a multiplication sign has been omitted, parentheses will be inserted automatically as shown in the examples below. • When a multiplication sign is omitted immediately before an open parenthesis or after a closed parenthesis. 6 ÷ 2 (1 + 2) p 6 ÷ (2 (1 + 2)) 6 ÷ A (1 + 2) p 6 ÷ (A (1 + 2)) 1 ÷ (2 + 3) sin(30) p 1 ÷ ((2 + 3) sin(30)) • When a multiplication sign is omitted immediately before a variable, a constant, etc. 6 ÷ 2π p 6 ÷ (2π) 2 ÷ 2'(2) p 2 ÷ (2'(2)) 4π ÷ 2π p 4π ÷ (2π) • When inputting a function that uses commas (such as Pol, Rec), be sure to input the closed parentheses required by the expression. If you do not input closed parentheses, parentheses may not be inserted automatically as described above. A Final Closed Parenthesis You can omit one or more closed parentheses that come at the end of a calculation, immediately before the w key is pressed. Example: (2 + 3) × (4 – 1) = 15 (2+3)* (4-1w ( 2+ 3 ) × ( 4– 1 15 A Scrolling the Screen Left and Right Input Expression 12345 + 12345 + 12345 345 + 12345 + 12345I Displayed Expression Cursor E-8 • While the b symbol is on the screen, you can use the d key to move the cursor to the left and scroll the screen. • Scrolling to the left causes part of the expression to run off the right side of the display, which is indicated by the \ symbol on the right. While the \ symbol is on the screen, you can use the e key to move the cursor to the right and scroll the screen. • You can also press f to jump to the beginning of the expression, or c to jump to the end. A Number of Input Characters (Bytes) As you input a mathematical expression, it is stored in memory called an “input area,” which has a capacity of 99 bytes. This means you can input up to 99 bytes for a single mathematical expression. Normally, the cursor that indicates the current input location on the display is either a flashing vertical bar (|) or horizontal bar ( ). When the remaining capacity of the input area is 10 bytes or less, the cursor changes to a flashing box (k). If this happens, stop input of the current expression at some suitable location and calculate its result. k Editing a Calculation A Insert Mode and Overwrite Mode The calculator has two input modes. The insert mode inserts your input at the cursor location, shifting anything to the right of the cursor to make room. The overwrite mode replaces the key operation at the cursor location with your input. Pressing + Original Expression Insert Mode 1+2|34 1+2+|34 1+2 3 4 1+2 + 4 Cursor Overwrite Mode Cursor The initial default input mode setting is insert mode. To change to the overwrite mode, press: 1D(INS). A Editing a Key Operation You Just Input Example: To correct 369 × 13 so it becomes 369 × 12 369*13 369 × 13I D2 369 × 12I E-9 A Deleting a Key Operation Example: To correct 369 × × 12 so it becomes 369 × 12 Insert Mode 369**12 ddD 369 ×× 12I 369 ×I12 Overwrite Mode 369**12 dddD 369 ×× 12 369 × 12 A Editing a Key Operation within an Expression With the insert mode, use d and e to move the cursor to the right of the key operation you want to edit, press D to delete it, and then perform the correct key operation. With the overwrite mode, move the cursor to the key operation you want to correct and then perform the correct key operation. A Inserting Key Operations into an Expression Be sure to select the insert mode whenever you want to insert key operations into an expression. Use d and e to move the cursor to the location where you want to insert the key operations, and then perform them. k Finding the Location of an Error If your calculation expression is incorrect, an error message will appear on the display when you press w to execute it. After an error message appears, press the d or e key and the cursor will jump to the location in your calculation that caused the error so you can correct it. Example: When you input 14 ÷ 0 × 2 = instead of 14 ÷ 10 × 2 = (The following examples use the insert mode.) 14/0*2w e or d Mat h ERROR 14 ÷ 0I×2 Location of Error d1w E-10 14 ÷ 10 × 2 28 Basic Calculations Unless otherwise noted, the calculations in this section can be performed in any of the calculator’s calculation mode, except for the BASE Mode. k Arithmetic Calculations Arithmetic calculations can be used to perform addition (+), subtraction (-), multiplication (*), and division (/). Example: 7 × 8 − 4 × 5 = 36 7*8-4*5w 36 k Fractions Fractions are input using a special separator symbol ({). A Fraction Calculation Examples Example 1: 3 Example 2: 1 2 11 +1 =4 4 3 12 3$1$4+ 1$2$3w 2 1 7 + = (Fraction Display Format: d/c) 3 2 6 2$3+1$2w 4{11{12 7{6 Note • If the total number of elements (integer + numerator + denominator + separator symbols) of a fraction calculation result is greater than 10 digits, the result will be displayed in decimal format. • If an input calculation includes a mixture of fraction and decimal values, the result will be displayed in decimal format. • You can input integers only for the elements of a fraction. Inputting non-integers will produce a decimal format result. A Switching between Mixed Fraction and Improper Fraction Format To convert a mixed fraction to an improper fraction (or an improper fraction to a mixed fraction), press !$(d/c). A Switching between Decimal and Fraction Format Press $ to toggle between decimal value and fraction display format. Note The calculator cannot switch from decimal to fraction format if the total number of fraction elements (integer + numerator + denominator + separator symbols) is greater than 10 digits. E-11 k Percent Calculations Inputting a value and with a percent (%) sign makes the value a percent. A Percent Calculation Examples Example 1: 2 % = 0.02 ( 2 ) 10 0 2!((%)w 002 150*20 !((%)w 30 Example 3: What percent of 880 is 660? 660/880 !((%)w 75 Example 2: 150 × 20% = 30 (150 × 20 ) 100 Example 4: Increase 2,500 by 15%. 2500+2500* 15!((%)w 2875 Example 5: Reduce 3,500 by 25%. 3500-3500* 25!((%)w 2625 Example 6: Reduce the sum of 168, 98, and 734 by 20%. 168+98+734w 1000 -G*20!((%)w 800 Example 7: 300 grams are added to a test sample originally weighing 500 grams, producing a final test sample of 800 grams. What percent of 500 grams is 800 grams? (500+300) /500!((%)w 160 Example 8: What is the percentage change when a value is increased from 40 to 46? (46-40)/40 !((%)w E-12 15 k Degree, Minute, Second (Sexagesimal) Calculations A Inputting Sexagesimal Values The following is basic syntax for inputting a sexagesimal value. {Degrees} $ {Minutes} $ {Seconds} $ Example: To input 2°30´30˝ 2$30$30$w 2 ˚ 30 ˚ 30 ˚ 2 ˚ 30 ˚ 30 • Note that you must always input something for the degrees and minutes, even if they are zero. A Sexagesimal Calculation Examples The following types of sexagesimal calculations will produce sexagesimal results. • Addition or subtraction of two sexagesimal values • Multiplication or division of a sexagesimal value and a decimal value Example: 2°20´30˝ + 39´30˝ = 3°00´00˝ 2$20$30$+ 0$39$30$w 3 ˚ 0˚ 0 A Converting between Sexagesimal and Decimal Pressing $ while a calculation result is displayed will toggle the value between sexagesimal and decimal. Example: To convert 2.255 to sexagesimal 2 ˚ 15˚ 18 2.255w$ Calculation History and Replay Calculation history maintains a record of each calculation you perform, including the expressions you input and calculation results. You can use calculation history in the COMP, CMPLX, and BASE Modes. k Accessing Calculation History The ` symbol in the upper right corner of the display indicates that there is data stored in calculation history. To view the data in calculation history, press f. Each press of f will scroll upwards (back) one calculation, displaying both the calculation expression and its result. Example: 1+1w2+2w3+3w 3+ 3 6 f 2+2 4 E-13 f 1+1 2 While scrolling through calculation history records, the $ symbol will appear on the display, which indicates that there are records below (newer than) the current one. When this symbol is turned on, press c to scroll downwards (forward) through calculation history records. Important! • Calculation history records are all cleared whenever you press p, when you change to a different calculation mode, and whenever you perform any reset operation. • Calculation history capacity is limited. Whenever you perform a new calculation while calculation history is full, the oldest record in calculation history is deleted automatically to make room for the new one. k Using Replay While a calculation history record is on the display, press d or e to display the cursor and enter the editing mode. Pressing e displays the cursor at the beginning of the calculation expression, while d displays it at the end. After you make the changes you want, press w to execute the calculation. Example: 4 × 3 + 2.5 = 14.5 4 × 3 – 7.1 = 4.9 4*3+2.5w d DDDD-7.1w 4×3+ 2 . 5 145 4 × 3 + 2 . 5I 4×3 –7 . 1 49 Calculator Memory Operations k Using Answer Memory (Ans) The result of any new calculation you perform on the calculator is stored automatically in Answer Memory (Ans). A Ans Update and Delete Timing When using Ans in a calculation, it is important to keep in mind how and when its contents change. Note the following points. • The contents of Ans are replaced whenever you perform any of the following operations: calculate a calculation result, add a value to or subtract a value from independent memory, assign a value to a variable or recall the value of a variable, or input statistical data in the SD Mode or REG Mode. • In the case of a calculation that produces more than one result (like coordinate calculations), the value that appears first on the display is stored in Ans. • The contents of Ans do not change if the current calculation produces an error. E-14 • When you perform a complex number calculation in the CMPLX Mode, both the real part and the imaginary part of the result are stored in Ans. Note, however, that the imaginary part of the value is cleared if you change to another calculation mode. A Automatic Insertion of Ans in Consecutive Calculations Example: To divide the result of 3 × 4 by 30 12 3*4w (Next) /30w Ans ÷ 30 04 Pressing / inputs Ans automatically. Note In the case of a function with parenthetical argument (page 8), Ans automatically becomes the argument only in the case that you input the function alone and then press w. A Inserting Ans into a Calculation Manually Example: To use the result of 123 + 456 in another calculation as shown below 123 + 456 = 579 789 – 579 = 210 123+456w 579 789-Kw 210 k Using Independent Memory Independent memory (M) is used mainly for calculating cumulative totals. If you can see the M symbol on the display, it means there is a non-zero value in independent memory. Independent memory can be used in all calculation modes, except for the SD Mode and the REG Mode. M symbol 10M+ A Adding to Independent Memory While a value you input or the result of a calculation is on the display, press m to add it to independent memory (M). Example: To add the result of 105 ÷ 3 to independent memory (M) 105/3m E-15 35 A Subtracting from Independent Memory While a value you input or the result of a calculation is on the display, press 1m(M–) to subtract it from independent memory (M). Example: To subtract the result of 3 × 2 from independent memory (M) 3*21m(M–) 6 Note Pressing m or 1m(M–) while a calculation result is on the display will add it to or subtract it from independent memory. Important! The value that appears on the display when you press m or 1m(M–) at the end of a calculation in place of w is the result of the calculation (which is added to or subtracted from independent memory). It is not the current contents of independent memory. A Viewing Independent Memory Contents Press tm(M). A Clearing Independent Memory Contents (to 0) 01t(STO)m(M) Clearing independent memory will cause the M symbol to turn off. k Using Variables The calculator supports six variables named A, B, C, D, X, and Y, which you can use to store values as required. Variables can be used in all calculation modes. A Assigning a Value or Calculation Result to a Variable Use the procedure shown below to assign a value or a calculation expression to a variable. Example: To assign 3 + 5 to variable A 3+51t(STO)-(A) A Viewing the Value Assigned to a Variable To view the value assigned to a variable, press t and then specify the variable name. Example: To view the value assigned to variable A t-(A) A Using a Variable in a Calculation You can use variables in calculations the same way you use values. Example: To calculate 5 + A 5+a-(A)w A Clearing the Value Assigned to a Variable (to 0) Example: To clear variable A 01t(STO)-(A) E-16 k Clearing All Memory Contents Perform the following key operation when you want to clear the contents of independent memory, variable memory, and Answer Memory. 19(CLR)1(Mem)w • If you do not want to clear the calculator’s settings, press A in place of w in the above operation. Scientific Function Calculations Unless otherwise noted, the functions in this section can be used in any of the calculator’s calculation modes, except for the BASE Mode. Scientific Function Calculation Precautions • When performing a calculation that includes a built-in scientific function, it may take some time before the calculation result appears. Do not perform any key operation on the calculator until the calculation result appears. • To interrupt and on-going calculation operation, press A. Interpreting Scientific Function Syntax • Text that represents a function’s argument is enclosed in braces ({ }). Arguments are normally {value} or {expression}. • When braces ({ }) are enclosed within parentheses, it means that input of everything inside the parentheses is mandatory. k Pi (π) and Natural Logarithm Base e The calculator supports input of pi (π) and natural logarithm base e into calculations. π and e are supported in all modes, except for the BASE Mode. The following are the values that the calculator applies for each of the built-in constants. π = 3.14159265358980 (1e(π)) e = 2.71828182845904 (Si(e)) k Trigonometric and Inverse Trigonometric Functions A Syntax and Input –1 –1 –1 sin({n}), cos({n}), tan({n}), sin ({n}), cos ({n}), tan ({n}) –1 Example: sin 30 = 0.5, sin 0.5 = 30 (Angle Unit: Deg) s30)w 05 1s(sin )0.5)w 30 –1 E-17 A Notes • These functions can be used in the CMPLX Mode, as long as a complex number is not used in the argument. A calculation like i × sin(30) is supported for example, but sin(1 + i) is not. • The angle unit you need to use in a calculation is the one that is currently selected as the default angle unit. k Angle Unit Conversion You can convert a value that was input using one angle unit to another angle unit. After you input a value, press 1G(DRG') to display the menu screen shown below. D R 1(D): Degrees 2(R): Radians 3(G): Grads G 1 2 3 Example: To convert π radians to degrees (Angle Unit: Deg) 2 (1e(π)/2) 1G(DRG')2(R)E ( π ÷2 ) r 90 k Hyperbolic and Inverse Hyperbolic Functions A Syntax and Input –1 –1 –1 sinh({n}), cosh({n}), tanh({n}), sinh ({n}), cosh ({n}), tanh ({n}) Example: sinh 1 = 1.175201194 ws(sinh)1)E 1175201194 A Notes • After pressing w to specify a hyperbolic function or 1w to specify an inverse hyperbolic function, press s, c, or t. • These functions can be used in the CMPLX Mode, but complex number arguments are not supported. k Exponential and Logarithmic Functions A Syntax and Input 10^({n}) .......................... 10 n e^({n}) ............................. e{n} log({n}) ........................... log10{n} log({m},{n}) ..................... log{m}{n} ln({n}) ............................. loge{n} { } (Common Logarithm) (Base {m} Logarithm) (Natural Logarithm) E-18 Example 1: log216 = 4, log16 = 1.204119983 4 l2,16)E l16)E l o g ( 16 ) 1204119983 Base 10 (common logarithm) is assumed when no base is specified.

Complex number arguments are also supported for these functions. 3 • ^(, '(, '(, x'( are also supported in the CMPLX Mode, but complex number arguments are not supported for these functions. E-19 k Coordinate Conversion (Rectangular ↔ Polar) Your calculator can convert between rectangular coordinates and polar coordinates. o o Rectangular Coordinates (Rec) Polar Coordinates (Pol) A Syntax and Input Rectangular-to-Polar Coordinate Conversion (Pol) Pol(x, y) x: Rectangular coordinate x-value y: Rectangular coordinate y-value Polar-to-Rectangular Coordinate Conversion (Rec) Rec(r, ) r: Polar coordinate r-value : Polar coordinate -value Example 1: To convert the rectangular coordinates (' 2, ' 2 ) to polar coordinates (Angle Unit: Deg) 1+(Pol)92) ,92))E 2 t,(Y) 45 (View the value of ) Example 2: To convert the polar coordinates (2, 30°) to rectangular coordinates (Angle Unit: Deg) 1-(Rec)2, 30)E 1732050808 t,(Y) 1 (View the value of y) A Notes • These functions can be used in the COMP, SD, and REG Modes. • Calculation results show the first r value or x value only. • The r-value (or x-value) produced by the calculation is assigned to variable X, while the -value (or y-value) is assigned to variable Y (page 16). To view the -value (or y-value), display the value assigned to variable Y, as shown in the example. • The values obtained for when converting from rectangular coordinates to polar coordinates is within the range –180°< < 180°. E-20 • When executing a coordinate conversion function inside of a calculation expression, the calculation is performed using the first value produced by the conversion (r-value or xvalue). Example: Pol (' 2, ' 2)+5=2+5=7 k Integration Calculation and Differential Calculation A Integration Calculation Your calculator performs integration using the Gauss-Kronrod method. Syntax and Input ∫ ( f (x), a, b, tol) f (x): a: b: tol: Function of X (Input the function used by variable X.) Lower limit of region of integration Upper limit of region of integration Error tolerance range –5 • This parameter can be omitted. In that case, a tolerance of 1 × 10 is used. e Example: ∫1 In( x ) = 1 fIa0(X)),1,aI(e))E ∫ ( I n ( X ) , 1, e ) 1 A Differential Calculation Your calculator approximates the derivative based on the central difference method. Syntax and Input d/dx( f (x), a, tol) f (x): Function of X (Input the function used by variable X.) a: Input value of point (differential point) of desired differential coefficient tol: Error tolerance range • This parameter can be omitted. In that case, a tolerance of 1 × 10 –10 is used. π for the function y = sin(x) (Angle Unit: Rad) Example: To obtain the derivative at point x = 2 1f(d/dx)sa0(X)), 1e(π)/2)E d/ dx ( s i n ( X ) , π ÷2 ) 0 A Integration and Differential Calculation Precautions • Integration and differential calculations can be performed in the COMP Mode and PRGM Mode (run mode: COMP) only. • The following cannot be used in f(x): Pol, Rec. The following cannot be used in f(x), a, b, or tol: ∫, d/dx. • When using a trigonometric function in f(x), specify Rad as the angle unit. E-21 • A smaller tol value increases precision, but it also increases calculation time. When specifying tol, use value that is 1 × 10–14 or greater. Precautions for Integration Calculation Only • Integration normally requires considerable time to perform. 1 • For f(x) 0 where a x b (as in the case of ∫0 3x2 – 2 = –1), calculation will produce a negative result. • Depending on the content of f(x) and the region of integration, calculation error that exceeds the tolerance may be generated, causing the calculator to display an error message. Precautions for Differential Calculation Only • If convergence to a solution cannot be found when tol input is omitted, the tol value will be adjusted automatically to determine the solution. • Non-consecutive points, abrupt fluctuation, extremely large or small points, inflection points, and the inclusion of points that cannot be differentiated, or a differential point or differential calculation result that approaches zero can cause poor precision or error. A Tips for Successful Integration Calculations When a periodic function or integration interval results in positive and negative f(x) function values Perform separate integrations for each cycle, or for the positive part and the negative part, and then combine the results. ∫ S Positive c a f(x)dx + (– ∫ b c f(x)dx) Positive Part Negative Part (S Negative) (S Positive) S Negative When integration values fluctuate widely due to minute shifts in the integration interval Divide the integration interval into multiple parts (in a way that breaks areas of wide fluctuation into small parts), perform integration on each part, and then combine the results. f (x) 0 ∫ a x1 x2 x3 x4 b x b a + ∫ f(x)dx = b x4 ∫ x1 a f(x)dx E-22 f(x)dx + ∫ x2 x1 f(x)dx + ..... k Other Functions x!, Abs(, Ran#, nPr, nCr, Rnd( The x!, nPr, and nCr functions can be used in the CMPLX Mode, but complex number arguments are not supported. A Factorial (!) Syntax: {n}! ({n} must be a natural number or 0.) Example: (5 + 3)! (5+3) 1X(x!)E 40320 A Absolute Value (Abs) When you are performing a real number calculation, Abs( simply obtains the absolute value. This function can be used in the CMPLX Mode to determine the absolute value (size) of a complex number. See “Complex Number Calculations” on page 25 for more information. Syntax: Abs({n}) Example: Abs (2 – 7) = 5 1)(Abs)2-7)E 5 A Random Number (Ran#) This function generates a three-decimal place (0.000 to 0.999) pseudo random number. It does not require an argument, and can be used the same way as a variable. Syntax: Ran# Example: To use 1000Ran# to obtain three 3-digit random numbers. 10001.(Ran#)E E E 287 613 118 • The above values are provided for example only. The actual values produced by your calculator for this function will be different. E-23 A Permutation (nPr)/Combination (nCr) Syntax: {n}P{m}, {n}C{m} Example: How many four-person permutations and combinations are possible for a group of 10 people? 101*(nPr)4E 5040 101/(nCr)4E 210 A Rounding Function (Rnd) You can use the rounding function (Rnd) to round the value, expression, or calculation result specified by the argument. Rounding is performed to the number of significant digits in accordance with the number of display digits setting. Rounding for Norm1 or Norm2 The mantissa is rounded off to 10 digits. Rounding for Fix or Sci The value is rounded to the specified number of digits. Example: 200 ÷ 7 × 14 = 400 (3 decimal places) (Internal calculation uses 15 digits.) 1Ne1(Fix)3 200/7E *14E 28571 400000 Now perform the same calculation using the rounding (Rnd) function.

Example: 10102 and 11002 = 10002 1010X(LOGIC)1(and)1100E 1000 b 11011 b 110 b A Logical Sum (or) Returns the result of a bitwise sum. Example: 10112 or 110102 = 110112 1011X(LOGIC)2(or)11010E A Exclusive Logical Sum (xor) Returns the result of a bitwise exclusive logical sum. Example: 10102 xor 11002 = 1102 1010X(LOGIC)e1(xor)1100E E-42 A Exclusive Logical Sum Negation (xnor) Returns the result of the negation of a bitwise exclusive logical sum. Example: 11112 xnor 1012 = 11111101012 1111X(LOGIC)3(xnor)101E 1111110101 b 1111110101 b 1111010011 b A Complement/Inversion (Not) Returns the complement (bitwise inversion) of a value. Example: Not(10102) = 11111101012 X(LOGIC)e2(Not)1010)E A Negation (Neg) Returns the two’s complement of a value. Example: Neg(1011012) = 11110100112 X(LOGIC)e3(Neg)101101)E Program Mode (PRGM) You can use the PRGM Mode to create and store programs for calculations you need to perform on a regular basis. You can include any calculation that can be performed in the COMP, CMPLX, BASE, SD, or REG Mode in a program. k Program Mode Overview A Specifying a Program Run Mode Though you create and run programs in the PRGM Mode, each program has a “run mode” that it runs in. You can specify COMP, CMPLX, BASE, SD, or REG as a program’s run mode. This means you need to think about what you want your program to do and select the appropriate run mode. A Program Memory Program memory has a total capacity of 390 bytes, which can be shared by up to four programs. Further program storage is not possible after program memory becomes full. k Creating a Program A Creating a New Program Example: To create a program that converts inches to centimeters (1 inch = 2.54 cm) ? → A : A × 2.54 E-43 1.

A Functions that Can be Input as Program Commands You can input the settings and other operations that you perform during normal calculations as program commands. For more information, see the “Command Reference” below. k Command Reference This section provides details on each of the commands that you can use in programs. Commands that have g in the title can be input on the screen that appears when you press !d(P-CMD) or 5. A Basic Operation Commands g ? (Input Prompt) Syntax Function Example ? → {variable} Displays the input prompt “{variable}?” and assigns the input value to a variable. ?→A → (Variable Assignment) Syntax Function Example {expression ; ?} → {variable} Assigns the value obtained by the element on the left to the variable on the right. A+5 → A : (Separator Code) Syntax Function Example {statement} : {statement} : ... : {statement} Separates statements. Does not stop program execution. 2 2 ? → A : A : Ans E-46 ^ (Output Command) Syntax Function Example {statement} ^ {statement} Pauses program execution and displays the result of the current execution. The Q symbol is turned on while program execution is paused by this command. 2 2 ? → A : A ^ Ans A Unconditional Jump Command g Goto ~ Lbl Syntax Function Example Goto n : .... : Lbl n or Lbl n : .... : Goto n (n = integer from 0 to 9) Execution of Goto n jumps to corresponding Lbl n. ? → A : Lbl 1 : ? → B : A × B ÷ 2 ^ Goto 1 Important! A Syntax ERROR occurs if there is no corresponding Lbl n in the same program where Goto n is located. A Conditional Jump Commands and Conditional Expressions g S Syntax Function Example 1 {expression} {relational operator} {expression} S {statement1} : {statement2} : .... 2 {expression} S {statement1} : {statement2} : .... Conditional branching command used in combination with relational operators (=, ≠, >, >, <, <). Syntax 1: {statement1} is executed if the condition to the left of the S command is true, and then {statement2} and everything after it is executed in sequence. {statement1} is skipped if the condition to the left of the S command is false, and then {statement2} and everything after it is executed. Syntax 2: A non-zero evaluation result of the condition to the left of the S command is interpreted as “true”, so {statement1} is executed, followed by {statement2} and everything after it in succession. A zero evaluation result of the condition to the left of the S command is interpreted as “false”, so {statement1} is skipped, and {statement2} and everything after it is executed. Lbl 1 : ? → A : A > 0 S '(A) ^ Goto 1 =, ≠, >, >, <, < (Relational Operators) Syntax Function Example {expression} {relational operator} {expression} These commands evaluate the expressions on either side, and return a value of true (1) or false (0). These commands are used in combination with the branching command S, and when structuring the {conditional expression} of If statements and While statements. See the entries for S (page 47), If statement (page 48), and While statement (page 49). E-47 Note These commands evaluate the expressions on either side, and return 1 if true and 0 if false, and store the result in Ans. A Control Structure Commands/If Statement g The If statement is used to control program execution branching according to whether the expression following If (which is the branching condition) is true or false. If Statement Precautions • An If must always be accompanied by a Then. Using an If without a corresponding Then will result in a Syntax ERROR. • An expression, Goto command, or Break command can be used for the {expression*} following Then and Else. If~Then (~Else) ~IfEnd Syntax Function Example 1 Example 2 If {conditional expression} : Then {expression*} : Else {expression*} : IfEnd : {statement} : ... • The statements following Then are executed up to Else, and then the statements following IfEnd are executed when the conditional statement following If is true. The statements following Else and then the statements following IfEnd are executed when the conditional statement following If is false. • Else {expression} may be omitted. • Always include the IfEnd:{statement}. Omitting it will not cause an error, but certain program contents can cause unexpected execution results by everything after the If statement. ? → A : If A < 10 : Then 10A ^ Else 9A ^ IfEnd : Ans×1.05 ? → A : If A > 0 : Then A × 10 → A : IfEnd : Ans×1.05 A Control Structure Commands/For Statement g The For statement repeats execution of the statements between For and Next as long as the value assigned to the control variable is within the specified range. For Statement Precautions A For statement must always be accompanied by a Next statement. Using a For without a corresponding Next will result in a Syntax ERROR. For~To~Next Syntax Function Example For {expression (starting value)} → {variable (control variable)} To {expression (ending value)} : {statement} : ... {statement} : Next : .... Execution of the statements from For to Next repeats as the control variable is incremented by 1 with each execution, starting from the starting value. When the value of the control value reaches the ending value, execution jumps to the statement following Next. Program execution stops if there is no statement following Next. 2 For 1 → A To 10 : A → B : B ^ Next E-48 For~To~Step~Next Syntax Function Example For {expression (starting value)} → {variable (control variable)} To {expression (ending value)} Step {expression (step)} : {statement} : ... {statement} : Next : .... Execution of the statements from For to Next repeats as the control variable is incremented by the step amount with each execution, starting from the starting value. Except for that, this command is the same as For~To~Next. 2 For 1 → A To 10 Step 0.5 : A → B : B ^ Next A Control Structure Commands/While Statement g While~WhileEnd Syntax Function Example While {conditional expression} : {statement} : ... {statement} : WhileEnd : .... The statements from While to WhileEnd are repeated while the conditional expression following While is true (non-zero). When the conditional expression following While becomes false (0), the statement following WhileEnd is executed. 2 ? → A : While A < 10 : A ^ A+1 → A : WhileEnd : A÷2 Note If the condition of the While statement is false the first time this command is executed, execution jumps directly to the statement following WhileEnd without executing the statements from While to WhileEnd even once. A Program Control Commands g Break Syntax Function Example .. : {Then ; Else ; S } Break : .. This command forces a break in a For or While loop, and jumps to the next command. Normally, this command is used inside of a Then statement in order to apply a Break condition. ? → A : While A > 0 : If A > 2 : Then Break : IfEnd : WhileEnd : A ^ A Setup Commands These commands function the same way as the calculator’s various setup settings. For more information, see “Calculator Setup” on page 6. Important! With some setup commands, the settings you configure remain in effect even after you finish running the program. E-49 Angle Unit Commands Deg, Rad, Gra Syntax Operation Function (COMP, CMPLX, SD, REG) .. : Deg : .. .. : Rad : .. .. : Gra : .. !,(SETUP)b(Deg) !,(SETUP)c(Rad) !,(SETUP)d(Gra) These commands specify the angle unit setting. Display Format Command Fix Syntax Operation Function (COMP, CMPLX, SD, REG) .. : Fix {n} : .. (n = an integer from 0 to 9) !,(SETUP)eb(Fix)a to j This command fixes the number of decimal places (from 0 to 9) for output of calculation results. Sci Syntax Operation Function (COMP, CMPLX, SD, REG) .. : Sci {n} : .. (n = an integer from 0 to 9) !,(SETUP)ec(Sci)a to j This command fixes the number of significant digits (from 1 to 10) for output of calculation results. Pressing !,(SETUP)ec(Sci) and then a specifies 10 significant digits. Norm Syntax Operation Function (COMP, CMPLX, SD, REG) .. : Norm {1 ; 2} : .. !,(SETUP)ed(Norm)b or c This command specifies either Norm1 or Norm2 for output of calculation results. Statistical Frequency Command FreqOn, FreqOff Syntax Operation Function (SD, REG) .. : FreqOn : .. .. : FreqOff : .. !,(SETUP)db(FreqOn) !,(SETUP)dc(FreqOff) This command turns statistical frequency on (FreqOn) or off (FreqOff). E-50 A Clear Commands ClrMemory Syntax Operation Function (COMP, CMPLX, BASE) .. : ClrMemory : .. !j(CLR)b(Mem) This command clears all variables to zero. Note To clear a specific variable, use 0 → {variable}. ClrStat Syntax Operation Function (SD, REG) .. : ClrStat : .. !j(CLR)b(Stat) This command clears all statistical sample data currently in memory. A Independent Memory Commands M+, M– Syntax Operation Function (COMP, CMPLX, BASE) .. : {expression} M+ : .. / .. : {expression} M– : .. l/!l(M–) M+ adds the value of the expression to independent memory, while M– subtracts it. A Rounding (Rnd) Command Rnd( Syntax Operation Function (COMP, CMPLX, SD, REG) .. : {expression} : Rnd(Ans : .. !a(Rnd) This command rounds a calculation result in accordance with the number of digits specified by the display format. A Number Base Commands Dec, Hex, Bin, Oct Syntax Operation Function (BASE) .. : Dec : .. / .. : Hex : .. / .. : Bin : .. / .. : Oct : .. x(DEC)/M(HEX)/l(BIN)/I(OCT) These commands specify the number base for base-n calculations. E-51 A Statistical Data Input Command DT Syntax (SD, REG) .. : {expression (x-value)} ; {expression (Freq-value)} DT : .. ..................SD Mode, FreqOn .. : {expression (x-value)} DT : .. ..................SD Mode, FreqOff .. : {expression (x-value)} , {expression (y-value)} ; {expression (Freq-value)} DT : .. ............... REG Mode, FreqOn .. : {expression (x-value)} , {expression (y-value)} DT : .. ............... REG Mode, FreqOff Important! To input a semicolon (;) in the above syntax, press !,(;). To input a comma (,), press ,. Operation Function l(Inputs DT.) Use this command to input one set of sample data. The DT command functions the same way as the l key (DT key) in the SD Mode and REG Mode. A Functions Not Supported in Programs The following functions are not supported inside of functions. • Calculation result conversion functions (ENG/, ENG,, Sexagesimal ↔ Decimal Conversion, Fraction ↔ Decimal Conversion) • Display switching (!w(Re⇔Im)) while a complex number calculation result is displayed • Reset (!j(CLR)d(All)w) • Setup information clear (!j(CLR)c(Setup) w) E-52 Appendix k Calculation Priority Sequence The calculator performs calculations you input in accordance with the priority sequence shown below. • Basically, calculations are performed from left to right. • Calculations enclosed in parentheses are given priority.

E-55 Mat h ERROR Sample Error Message A Recovering from an Error Message You can recover from an error message by performing the key operations described below, regardless of the error type. • Press d or e to display the editing screen for the calculation expression you input immediately before the error occurred, with the cursor positioned at the location that caused the error. For more information, see “Finding the Location of an Error” on page 10. • Pressing A will clear the calculation expression you input immediately before the error occurred. Note that a calculation expression that causes an error will not be included in calculation history. A Error Message Reference This section lists all of the error messages that the calculator displays, as well as their causes and what you need to do to avoid them. Math ERROR Cause • An intermediate or the final result of the calculation falls outside of the allowable calculation range. • An input value is outside the allowable input range. • You are trying to perform an illegal mathematical operation (such as division by zero). Action • Check your input values and reduce the number of digits, if required. • When using independent memory or a variable as the argument of a function, make sure that the memory or variable value is within the allowable range for the function. For information about the allowable value input range, see “Calculation Ranges, Number of Digits, and Precision” on page 54. Stack ERROR Cause The calculation has causes the capacity of the numeric stack or the command stack to be exceeded. Action • Simplify the calculation expression so it does not exceed the capacity of the stacks. • Try splitting the calculation into two or more parts. Syntax ERROR Cause The calculation has a format problem. Action Check the syntax and make the required corrections. Argument ERROR Cause The calculation has a problem with how an argument being used. Action Check how arguments are being used and make the required corrections. E-56 Time Out Error Cause The current differential or integration calculation ends without the ending condition being fulfilled. Action Differential or integration calculation: Try increasing the tol value. Note that this also decreases solution precision. Data Full Cause You are attempting to store sample data in the SD Mode or REG Mode when the allowable number of data samples are already stored in memory. Action Keep the number of data samples within the allowable limit. For more information, see “Maximum Number of Input Data Items” on page 29. Go ERROR Cause A program (that you created in the PRGM Mode) has a “Goto n” command without a corresponding “Lbl n” label. Action Either add a “Lbl n” for the “Goto n” command, or delete the applicable “Goto n” command. k Before assuming malfunction of the calculator... Perform the following steps whenever an error occurs during a calculation or when calculation results are not what you expected. If one step does not correct the problem, move on to the next step. Note that you should make copies of important copies of important data before performing these steps. 1 Check the calculation expression to make sure it does not include any errors. 2 Make sure that you are using the correct mode for the type of calculation you are trying to perform. 3 If the above steps do not restore normal operation, press the p key. The calculator will perform a self-check of its status as it starts up. If the calculator discovers a problem, it will return its calculation mode and setup to their initial defaults, and clear all data currently in memory. 4 If step 3 does not restore normal operation, initialize all modes and settings by pressing !j(CLR)c(Setup)w. Power Requirements A Replacing the Battery Dim figures on the display of the calculator indicate that battery power is low. Continued use of the calculator when the battery is low can result in improper operation. Replace the battery as soon as possible when display figures become dim. Even if the calculator is operating normally, replace the battery at least once every three years. Important! Removing the battery will cause all of the calculator’s memory contents to be deleted. E-57 1. Press 1A(OFF) to turn off the calculator. • To ensure that you do not accidentally turn on power while replacing the battery, slide the hard case onto the front of the calculator. Screw 2.
