```REMQUO(3)						     Linux Programmer's Manual							 REMQUO(3)

NAME
remquo, remquof, remquol - remainder and part of quotient

SYNOPSIS
#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)):

remquo(), remquof(), remquol():
_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.

The value of the remainder is the same as that computed by the remainder(3) function.

The value stored via the quo pointer has the sign of x / y and agrees with the quotient in at least the low order 3 bits.

For example, remquo(29.0, 3.0) returns -1.0 and might store 2.  Note that the actual quotient might not fit in an integer.

RETURN VALUE
On success, these functions return the same value as the analogous functions described in remainder(3).

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

If x is an infinity, and y is not a NaN, a domain error occurs, and a NaN is returned.

If y is zero, and x is not a NaN, a domain error occurs, and a NaN is returned.

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.
