HEXADECIMAL AND DECIMAL CONVERSION
To find the decimal number, locate the hex number and its decimal equivalent for each position_ Add these to obtain the decimal number. To find the hex number, locate the next lower decimal number and its hex equivalent. Each difference is used to obtain the next hex number until the entire number is developed.
