Integer
/ˈɪn-tɪ-dʒər/
noun — “a number that refuses decimals, refuses ambiguity, and generally prefers to stay whole.”
Integer is a numeric type used in computing to represent whole numbers without fractional parts. Unlike floating-point values, integers are exact within their range: no rounding, no approximation, no hidden binary drift from rounding error. If a value is an integer, it is either fully representable or it simply does not fit.
