From my CMULISP 17f running under Irix 5.3:

    * (- 0.0 #C( 1.0 1.0))
    #C(-1.0 1.0)              WRONG!

Also: 

    *  (/ 2.0 #C(-1.0 -1.0))
    #C(-1.0 1.0)              WRONG!

Evidently a real first argument to - not getting properly
coerced to a complex! The / case is really puzzling.

However it works right for *:

    * (* 2.0 #C(-1.0 -1.0))
    #C(-2.0 -2.0)

Has anyone else seen this? Any fixes?

Regards,
Richard Hodges
