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


     remquo, 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


     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 remain-
     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)  returns -1.0 and might store 2.  Note
     that the actual quotient might not fit in an integer.


     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


     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.


     These functions first appeared in glibc in version 2.1.
