Number Systems

This appendix describes the four numbering systems the Mini-PLC-2/05
processor uses:

decimal
octal
binary
hexadecimal

These numbering systems differ by their number sets and place values.

Decimal Numbering System

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 A.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.
