remquo, remquof, remquol - remainder from division

Syntax	#include <math.h> C11 double remquo(double x, double y, int *quo); float remquof(float x, float y, int *quo); long double remquol(long double x, long double y, int *quo); (End)
Description	These functions compute the same remainder as the remainder()-functions, respectively. In the variable pointed to by quo, they store the value of the division x/y modulo 2**31 with the sign of the quotient.
Return val.	Floating-point remainder = x-ny
		if y != 0.
	HUGE_VAL HUGE_VALF HUGE_VALL	depending on the function type, if y = 0.                        errno wird gesetzt, um den Fehler anzuzeigen.
Errors	remquo(), remquof() and remquol() will fail if:
	EDOM	y = 0 .
