Whole number

A whole number is an intuitive concept of a number that is not fractional. There are three different definitions of the whole numbers, whose usage depends heavily on the author:

  1. The natural numbers.

  2. The natural numbers and zero (in definitions of the number sets where the natural numbers do not contain zero).

  3. The integers.

The set of whole numbers, when it is separate from the natural numbers and the integers, is usually notated as either \(\mathbb{N}^0\) or \(\mathbb{W}\).
