The abstract says that
0=< D mod d < |d|
i.e., the remainder is always positive irrespective of the signs of D
(dividend) and d (divisor). It probably makes a difference in very
few cases because in most cases when we care for the remainder, d is
positive, and this definition has the same result as FM/MOD. Still,
one could add EM/MOD without problems. Any ideas on how to implement
it efficiently based on UM/MOD or SM/REM?
