scsimp broken?



Good day,


It would appear that scsimp can't simplify something very simple like 
sqrt(2)/2-1/sqrt(2).

Is there any use in having scsimp in the first place when ratsimp seems 
to outperform it all the time?

(C15) g(1/2);

                               SQRT(2)      1
(D15)                          ------- - -------
                                  2      SQRT(2)
(C16) float(%);

(D16)                        1.110223024625157E-16
(C17) scsimp(D15);

                               SQRT(2)      1
(D17)                          ------- - -------
                                  2      SQRT(2)
(C18) ratsimp(D15);
