Hi there,

I while ago I wrote a trig library to do all sqrt, sin, cos, tan, arcsin,
arctan, and arccos using fixed point integer maths & lookup tables, it may
be of some use.
Here's a link to the page.

there are a few inaccuracies in the look up table (due to using a value of
3.142 for PI in the lookup tables), but it was fairly nippy.

cheers

Nick
