Description

   The remquo(), remquof(),  and remquol() functions compute
   the same remainder as the remainder(), remainderf(),  and
   remainderl() functions, respectively. In the object pointed to
   by quo, they store a value whose sign is the sign of x/y and
   whose magnitude is congruent modulo 2n to the magnitude of the
   integral quotient of x/y, where n is an implementation-defined
   integer greater than or equal to 3.

   The remquo functions are functionally equivalent to the remainder
   functions.
