- 1整數
An integer is a whole number, with no fraction and no extra decimal part: −3, 0, 1, 44. Half of something is not an integer; 2.7 is not an integer. Zero counts, and negative whole numbers count. This is maths-class English. In ordinary life people say whole number. In computing, an integer is also a kind of value the machine stores; mixing it with numbers that have decimal points is a classic way to get a wrong answer. The Latin behind it meant “whole” or “untouched,” but English does not use integer that way in daily speech anymore.

組成Borrowed from Latin integer, “whole, untouched.” English entire and French entier are doublets — same Latin word, different path. Further back it belongs with words for touching, such as tact.
