drem − floating-point remainder function
#include <math.h>
double drem(double x, double y);
The drem() 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 to the nearest integer. If the quotient is 1/2, it is rounded to the even number.
The drem() function returns the remainder, unless y is zero, when the function fails and errno is set.
