Implementation of exponential. Not tested, don't even know if it works at all.
Cut the trig table sizes in 4 w/ symmetry, etc.
Lazy implementations of sine and tangent (that justuse cosine indirectly).
Addressed edge cases.
Needs EXTENSIVE testing to get a good grip on error bounds.
Initial pass at a 32-bit fixed point library.
- Generated cosine / sine tables, put them in PROGMEM
- Wrote initial quadratic interpolation cosine function. ... not safe to use yet, but it seems to work for non-edge cases. Need to write a better way to test it.
