flremquo x yprocedure

Returns two values, the rounded remainder of x/y and the low-order n bits (as a correctly signed exact integer) of the rounded quotient. The value of n is implementation-dependent but at least 3. This procedure can be used to reduce the argument of the inverse trigonometric functions, while preserving the correct quadrant or octant. (C99 remquo)
