Whole number

[summary: An intuitive concept of a number that is not fractional. Depending on the author, the set of whole numbers is defined as either the natural numbers, the natural numbers and [-zero], or the integers.]

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}$~$.
