whole number

    (Or "whole number") One of the numbers in the set

   	..., -3, -2, -1, 0, 1, 2, 3, ...

   There are an infinite number of integers, though each one is
   finite.

   An inductive definition of an integer is a number that is either
   zero or an integer plus or minus one.  An integer has no
   fractional part.  If written as a real number, e.g. 42.0, the
   part after the decimal point will be zero.

   A natural number is a non-negative integer.

   Computers usually store integers in binary.  Natural numbers can
   be stored as unsigned integers and integers that may be negative
   require a sign bit and typically use twos complement
   representation.  Other representations have been used, such as
   binary-coded decimal.
