Appendix B: Decimal/Hexadecimal/Conversions

The decimal (base 10) numbering system represents each position in successive powers of 10, with each decimal symbol having a value from 0 to 9. The hexadecimal (base 16) numbering system represents each position in successive powers of 16 with each hex symbol having a value of 0 to 15. Since each hex position must have a single symbol, the symbols "A" through "F" are assigned to values 10 through 15 respectively. Refer to Table 1. The information and examples to follow will explain how to convert from a decimal number to a hexadecimal number and vice versa.
