Mathematical Library Functions remquo(3M)
NAME
remquo, remquof, remquol - remainder functions
SYNOPSIS
c99 [ flag... ] file... -lm [ library... ]
#include
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 remain-
derl() 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 0and 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 callfeclearexcept(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 returnSunOS 5.11 Last change: 12 Jul 2006 1
