       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 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.


       On  success, these functions return the same value as the analogous functions described in

       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.


       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.
