The set of negative integers is represented below:


-\infty,\cdots-2,-1

The set of positive integers is represented as:


1,2,\cdots\infty

Combining the two sets above and adding zero (0), we have:


-\infty,\cdots-2,-1,0,1,2\cdots,\infty

The set which describes the set of negative, zero or positive whole numbers is the set of integers.

Thus the change will be an integer number.
