MathLib is not required for the use of PocketC itself, however many floating point
functions return 0 if MathLib is not synched to your PalmPilot. The symptom is
hour line angles are all 0, and graphs of hour lines are vertical.

MathLib is a free shared library that can be used by any OS 2.0 Pilot program
that needs IEEE 754 double precision math functions. It's distributed under the
terms of the GNU General Public License, and is freely available with full
source code and documentation at the MathLib Information web page. It's not a
part of the PocketC program, nor of any Illustrating Shadows code, and you're not 
paying anything for its use; a copy is simply included in this archive for your 
convenience.
