--- layout: stdlib-reference --- # fmod ## Description Floating point remainder of x/y. The floating-point remainder is calculated such that x = i * y + f, where i is an integer, f has the same sign as x, and the absolute value of f is less than the absolute value of y. ## Signature

T fmod<T>(
    T x,
    T y)
    where T : __BuiltinFloatingPointType;

vector<T, N> fmod<T, N:int>(
    vector<T, N> x,
    vector<T, N> y)
    where T : __BuiltinFloatingPointType;

matrix<T, N, M> fmod<T, N:int, M:int>(
    matrix<T, N, M> x,
    matrix<T, N, M> y)
    where T : __BuiltinFloatingPointType;
