NAME
remquo, remquof, remquol - remainder and part of quotientSYNOPSIS
#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 );
Feature Test Macro Requirements for glibc (see feature_test_macros(7)):
_XOPEN_SOURCE >= 600 || _ISOC99_SOURCE || _POSIX_C_SOURCE >= 200112L;
or
cc -std=c99
DESCRIPTION
These functions compute the remainder and part of the quotient upon division of x by y. A few bits of the quotient are stored via the quo pointer. The remainder is returned as the function result.RETURN VALUE
On success, these functions return the same value as the analogous functions described in remainder(3).ERRORS
See math_error(7) for information on how to determine whether an error has occurred when calling these functions.The following errors can occur:
- Domain error: x is an infinity or y is 0, and the other argument is not a NaN
- An invalid floating-point exception ( FE_INVALID) is raised.
These functions do not set errno.
VERSIONS
These functions first appeared in glibc in version 2.1.CONFORMING TO
