DESCRIPTION

     The remquo() functions compute the value r such that r = x - n*y, where n
     is the integer nearest the exact value of x/y.

     If there are two integers closest to x/y, n shall be the even one. If r
     is zero, it is given the same sign as x.  This is the same value that is
     returned by the remainder() function.  remquo() also calculates the lower
     seven bits of the integral quotient x/y, and gives that value the same
     sign as x/y. It stores this signed value in the object pointed to by quo.

SPECIAL VALUES

     remquo(x, y, quo) returns a NaN and raises the "invalid" floating-point
     exception if x is infinite or y is 0.
