This may be a silly question, and the answer is just for curiosity... What
is the purpose of the pfMath functions? I was told in Performer class that
they were faster than the standard math functions and thus better to use in
Real Time programming, yet on our Onyx IR (16 processors) I ran some timing
tests and it seemed that the standard math routines <math.h> ran 20%
faster.... Is there another reason other than speed for using the pfMath
routines?

     Just me, just curious... (and don't tell me what happened to the cat
<grin>)
