Number Systems
This appendix describes the four numbering systems the processor uses:
decimal
octal
binary
hexadecimal
These numbering systems differ by their number sets and place values.
Timers, counters and math operations word values use the decimal
numbering system. This is a numbering system made up of ten digits: the
numbers 0 through 9 (Table C.A). All decimal numbers are composed of
these digits. The value of a decimal number depends on the digits used
and the place value of each digit.

Each place value in a decimal number represents a power of ten starting
with ten raised to the zero power (10
0
=1) (Figure C.1). You can compute
the decimal value of a number by multiplying each digit by its
corresponding place value and adding these numbers together.
