In mathematics, integers are the natural numbers and their negatives. Integers can also be shown on a number line as follows:

{...-4, -3, -2, -1, 0, +1, +2, +3, +4,...}\,\!

In particular, zero is also an integer, but it is not positive nor negative. "Integer" is another word for "whole". An integer is a rational number with no "fraction", or part. An integer is a decimal number with all zeros after the decimal separator. For example, the integer 17 is the same as the decimal 17.0 or 17.0000. view more...
