My dictionary defines number as: 'A concept of quantity that is or can be derived from a single unit, the sum of a collection of units, or zero.' So, yes zero is a number. Mar 31 02, 11:52 AM

In binary 0 is the absence of one. In all other systems it is the absence of numbers within that system. You try counting to zero. Zero is not a number Mar 31 02, 9:08 PM
