--- 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, int N>(
vector<T, N> x,
vector<T, N> y)
where T : __BuiltinFloatingPointType;
matrix<T, N, M> fmod<T, int N, int M>(
matrix<T, N, M> x,
matrix<T, N, M> y)
where T : __BuiltinFloatingPointType;
## Generic Parameters
