DESCRIPTION

     The remainder() 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.

SPECIAL VALUES

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