whole number in mathematics
A whole number without any decimal or fraction, like −2, 0, 5, or 100.
Schéma d’usage :
an integer between [number] and [number]
Erreur fréquente :
Learners sometimes think that decimals like 3.5 or fractions like 1/2 are integers. Integers are only whole numbers (…−2, −1, 0, 1, 2…). Learners may also confuse “integer” with the more general word “number”, which includes fractions and decimals.
Synonymes

whole-number data type in computing
In computer programs, a kind of value that can store whole numbers only, not decimals.
Schéma d’usage :
an integer variable that stores [number]
Erreur fréquente :
Learners sometimes confuse the mathematical meaning of “integer” with the programming data type and may not realize that different programming languages limit the size of an integer, which can cause errors like integer overflow.
Synonymes
int (Common abbreviation and type name in many programming languages; informal shorthand for “integer”.)
Antonymes
string (In programming, a string stores text, which contrasts with an integer that stores numeric whole values.)

Exemples
- The bug was caused by integer overflow when the counter passed two billion.
- To avoid integer overflow, we switched to a 64-bit integer type.
integer part
1/ˈɪntəd͡ʒɚ pˈɑɹt/
fixed phrase
technical
whole-number portion of a value
