# %(_:_:) Returns the remainder of dividing the first value by the second. ``` static func % (lhs: Self, rhs: Self) -> Self ``` ## Parameters `lhs` The value to divide. `rhs` The value to divide `lhs` by. `rhs` must not be zero. ## Discussion The result of the remainder operator (`%`) has the same sign as `lhs` and has a magnitude less than `rhs.magnitude`. ``` let x = 22 % 5 // x == 2 let y = 22 % -5 // y == 2 let z = -22 % -5 // z == -2 ``` For any two integers `a` and `b`, their quotient `q`, and their remainder `r`, `a == b * q + r`. --- Copyright © 2026 Apple Inc.
