Information about the MathLib library MathLib is a free shared library that can be used by any OS 2.0+ Palm program that needs IEEE 754 double precision math functions. It is distributed under the terms of the GNU Library General Public License, and is freely available with full source code and documentation at the MathLib Information webpage: http://www.radiks.net/~rhuebner/mathlib.html It's not a part of the Cetus GPS project, and you're not paying anything for its use; a copy is simply included in the Cetus GPS zip archive for your convenience. Many Palm programs uses the MathLib library, so it might be installed on you Palm already. In any case no harm is done installing it again, it will just overwrite the existing copy. Thanks to Rick Huebner who created MathLib, it has been a great help being able to use the math functions available in the library.
