Introduction to Integers

An integer is defined as a number with no fractional part. In other words, we can count forward and backward using integers. Going from one integer to the next is a discrete jump of one unit, with no stopping part of the way there. Integers are the numbers we get from rounding fractional numbers up or down to the nearest whole.

Types of Integers

Integers are of two types: positive and negative. On a number line or coordinate graph, positive integers are to the right of or above the zero point and negative integers are to the left or below.

Practical Uses of Integers

Integers are used in computer programming and coding, where things must be on or off, that is, 1 or 0. We call this “binary” because everything a computer does can be turned into a sequence of ones and zeroes.
