I have been looking around at stuff for some time, and I have found many people saying different things about the Pic Microcontroller. Some people have said that division is slow w/o hardware support, some have said that floating point operations were ridiculously painful, etc.

I am looking a for a vaguely comprehensive guide as to what mathematical operations are slow and what operations are fast. Over here, we have found an excellent approximation for cosine, which uses only square roots, multiplication, and division.

If anyone has any related info, could you please post?

Thank you.
