       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.

       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.

       remquo, remquof, remquol - remainder and part of quotient

       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 returned.
