Is there a trig module that I haven't found? I'm starting to work on a fast sine function, similar to some of this discussion.

Since Tools version 12 and later it is possible to include the "math.h" in xc files.
You do not need to write c-files when you need floating point and sin, cos etc anymore.
The computations is still translated to be run on a fixed Point CPU, so each Floating point instruction will take many CPU cycles to complete, but it is simple to use.
There is also some code on GitHub with lower precision but that is faster.
