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. |
