I've got a library of various 32 bit fixed point and 24 bit floating point
PIC routines I've needed over the years.  The Microchip app notes were so
poorly written (practically no comments, etc) a few years ago when I
needed the first routine that I wrote them myself.  These work with my PIC
development environment, general register model, etc.

I have not made these public so far and probably won't.  However, I would
be happy to license the source code and customize them as needed - for a
fee of course.
