rem_euclid

fn rem_euclid(int a, int b) -> int

use num::{rem_euclid};

Returns the remainder of a / b that is never negative: 0 <= r < abs(b).

Unlike %, whose result takes the sign of a. Panics with division by zero when b is 0.

Parameters#

Returns#

int

Examples#

use num::{rem_euclid};
use tests::assert;
assert!(rem_euclid(-7, 3) == 2);
assert!(-7 % 3 == -1);
