Talk:Whole numbers

Whole numbers are defined differently by various mathematicians, have a look here. We should - perhaps - include the same advice as WolframMathWorld does: "Due to lack of standard terminology, the following terms are recommended in preference to "counting number," "natural number," and "whole number.""

set	name	symbol
..., -2, -1, 0, 1, 2, ...	integers	<math>\mathbb{Z}</math>
1, 2, 3, 4, ...	positive integers	<math>\mathbb{Z}^+</math>
0, 1, 2, 3, 4, ...	nonnegative integers	<math>\mathbb{Z}^*</math>
0, -1, -2, -3, -4, ...	nonpositive integers
-1, -2, -3, -4, ...	negative integers	<math>\mathbb{Z}^-</math>

Personally, I view the whole numbers as <math>\mathbb{Z}</math>, but try to avoid the term, and use the term integer instead... --BRichtigen 16:51, 19 November 2008 (EST)
