Calculates the floating-point remainder.

#include <math.h>

double fmod (double x, double y);

Parameters

x, y

Floating-point values.

Remarks

Calculates f of x/y such that:

x = i * y + f

Where:

i

An integer.

f

The floating-point remainder. f has the same sign as x, and the absolute value of f is less than the absolute value of y.

Return Values
