EXADECIMAL
Hexadecimal is a base-16 numbering system that uses the numbers
0 through 9 and the letters A through F. The letter A is equivalent to decimal
10, and F is equivalent to decimal 15. On the other hand, the letters AA are
equivalent to decimal 170, and FF is equivalent to decimal 255.
Hexadecimal is used to express binary values where four or more binary
digits are present. For example, when expressing the binary value established
by an eight-position DIP switch, the hexadecimal digit on the right expresses
the value of switch positions 1 through 4, and the hexadecimal digit on the
left expresses the value of switch positions 5 through 8.
Decimal, binary, and hexadecimal equivalents are shown in
