fmod − floating-point remainder function
#include <math.h>
double fmod(double x, double y);
The fmod() function computes the remainder of dividing x by y. The return value is x - n * y, where n is the quotient of x / y, rounded towards zero to an integer.
The fmod() function returns the remainder, unless y is zero, when the function fails and errno is set.
