NAMEremquo, remquof, remquol - remainder and part of quotient
#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():
- _ISOC99_SOURCE || _POSIX_C_SOURCE >= 200112L
DESCRIPTIONThese functions compute the remainder and part of the quotient upon division of xby y. A few bits of the quotient are stored via the quopointer. 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 quopointer has the sign of x / yand agrees with the quotient in at least the low order 3 bits.
RETURN VALUEOn success, these functions return the same value as the analogous functions described in remainder(3).
If xor yis a NaN, a NaN is returned.
If xis an infinity, and yis not a NaN, a domain error occurs, and a NaN is returned.
ERRORSSee 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.
VERSIONSThese functions first appeared in glibc in version 2.1.
