radix

- The base, or the number of digits used, in a
__numbering system__. For example, 2 in the__binary system__or 10 in the__decimal system__. The radix also serves as the multiplier within its numbering system. In the__decimal__system, for instance, each single position movement to the right of a digit represents a__division__by 10, while a movement to the left is a multiplication by 10. This can be seen, for example, in the number 153, where the 1 is in the hundreds position, the 5 is the tens, and the 3 is the units. Also called radix number, base (__8__), or base number.
