Bryan,

I'm confused.  The functions sin and cos evaluate to values in the range
-1 to 1.  What do you mean by three-byte INTEGERS?  Do you really just
want the sign of the function?

Assuming that what you really want is a floating or fixed point real,
how much precision does the CCS C compiler give you?  How many bits of
accuracy do you need?  How fast do you need it to be?

Regards,

Dave
