    /* The ANSI standard says that |QUOT| <= |NUMER / DENOM|, where
       NUMER / DENOM is to be computed in infinite precision.  In
       other words, we should always truncate the quotient towards
       zero, never -infinity.  Machine division and remainer may
       work either way when one or both of NUMER or DENOM is
       negative.  If only one is negative and QUOT has been
       truncated towards -infinity, REM will have the same sign as
       DENOM and the opposite sign of NUMER; if both are negative
       and QUOT has been truncated towards -infinity, REM will be
       positive (will have the opposite sign of NUMER).  These are
       considered `wrong'.  If both are NUM and DENOM are positive,
       RESULT will always be positive.  This all boils down to: if
       NUMER >= 0, but REM < 0, we got the wrong answer.  In that
       case, to get the right answer, add 1 to QUOT and subtract
       DENOM from REM.  */
