All About Numbers

What do integers include?

Integers include the whole numbers (also called positive integers or natural numbers), negative whole numbers (also called negative integers or the negatives of the naturals), and zero. Numbers such as 3/4, 5.993, 6.2, -3.2, and pi (π ; or 3.14 …) are not considered integers. Only integers are used when speaking of odd and even numbers (zero is considered to be an even number; for more about zero, see below).
