Compute the floating point remainder
#include <math.h> double remainder( double x, double y ); float remainderf( float x, float y ); long double remainderl( long double x, long double y );
These functions return the floating point remainder r = x - ny, where y is nonzero. The value n is the integral value nearest the exact value x/y. When |n - x/y| = ½, the value n is chosen to be even.
The behavior of remainder() is independent of the rounding mode.
The floating point remainder r = x - ny, where y is nonzero. If x is infinite or y is zero and the other is non-NaN, these functions return NaN.
