Word origin

整 (zhěng, "whole") + 数 (shù, "number") forms a term for a number with its parts kept whole rather than divided into fractions.

Usage tips

  • In English-language school math, whole number usually covers zero and positive counting numbers only, so integer is the safer term when a negative value is included.
