REMQUO
Linux Programmer's Manual (3)
20100920
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);
Link with lm.
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 floatingpoint exception
(FE_INVALID)
is raised.
These functions do not set
errno.
VERSIONS
These functions first appeared in glibc in version 2.1.
CONFORMING TO
C99, POSIX.12001.
