REMQUO(3) Linux Programmer's Manual REMQUO(3)[top]NAMEremquo, 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); Link withFeature 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-lm.DESCRIPTIONThese 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 remainā der(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) returnsand might store 2. Note that the actual quotient might not fit in an integer.-1.0RETURN VALUEOn 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.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. These functions do not set errno.VERSIONSThese functions first appeared in glibc in version 2.1.CONFORMING TOC99, POSIX.1-2001.SEE ALSOfmod(3), logb(3), remainder(3)COLOPHONThis page is part of release 3.55 of the Linux man-pages project.
