operator.floordiv

arithmetic

Return a // b — floor division (the functional form of `//`).

Syntax

operator.floordiv(a, b)

Rounding goes down, towards minus infinity, not towards zero: floordiv(-7, 2) is -4, not -3 as in C or Java. With floats the result is a float too: floordiv(7.5, 2) gives 3.0. When you need both quotient and remainder, divmod returns them in one call and guarantees the pair is consistent.

Examples

import operator
print(operator.floordiv(7, 2))   # → 3
print(operator.floordiv(7, 2) == 7 // 2)   # → True
print(operator.floordiv(-7, 2))   # → -4
print(list(map(operator.floordiv, [10, 20, 30], [3, 3, 4])))   # → [3, 6, 7]
print(operator.floordiv(1, 0))   # → ZeroDivisionError
