remquo

remquo(3M)						  Mathematical Library Functions						remquo(3M)

NAME

       remquo, remquof, remquol - remainder functions

SYNOPSIS

       cc [ flag... ] file... -lm [ library... ]
       #include <math.h>

       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);

DESCRIPTION

       The  remquo(),  remquof(), and remquol() functions compute the same remainder as the remainder(), remainderf(), and remainderl() functions,
       respectively. See remainder(3M). In the object pointed to by quo, they store a value whose sign is the sign of x/y and whose  magnitude	is
       congruent modulo 2**n to the magnitude of the integral quotient of x/y, where n is an integer greater than or equal to 3.

RETURN VALUES

       These functions return x REM y.

       If x or y is NaN, a NaN is returned.

       If x is +-Inf or y is 0 and the other argument is non-NaN, a domain error occurs and a NaN is returned.

ERRORS

       These functions will fail if:

       Domain Error    The x argument is Inf or the y argument is 0 and the other argument is non-NaN.

		       If  the	integer  expression  (math_errhandling & MATH_ERREXCEPT) is non-zero, then the invalid floating-point exception is
		       raised.

USAGE

       An application wanting to check for exceptions should call feclearexcept(FE_ALL_EXCEPT) before  calling	these  functions.  On  return,	if
       fetestexcept(FE_INVALID	|  FE_DIVBYZERO  |  FE_OVERFLOW  |  FE_UNDERFLOW) is non-zero, an exception has been raised. An application should
       either examine the return value or check the floating point exception flags to detect exceptions.
