integers
Numbers without fractions
Integers are whole numbers—positive, negative, or zero—without fractional or decimal components.
The set includes ..., -3, -2, -1, 0, 1, 2, 3, ... extending infinitely in both directions.
In programming, integer often refers to a data type that stores whole numbers: The function returns an integer.
Contrast with fractions, decimals, and floating-point numbers.
