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.
