integer

Integer is a math term for a number that is a whole number. In the equation 2 + 1/2, the number 2 is the integer and 1/2 is the fraction.

Integer comes from a 16th century Latin word meaning "whole" or "intact." For a number to be considered an integer, it must be whole — no fractions or decimals here. An integer can be positive or negative. The numbers 0, 1, 2, -1, and -2 are all examples of integers.
