From R. Huebner:
MathLib is a PalmOS shared library which makes a complete set of IEEE-754 double-precision math functions available to other PalmPilot applications. These functions include all the standard routines normally accessed by including ""math.h"" on other systems, including trigonometry (with inverse and hyperbolic), logarithms, exponentiation, and miscellaneous helper functions. The only standard routines I left out were the Bessel and Gamma functions, which had the poor taste to be both very large and very rarely used. These routines have been ported from the GCC 22.214.171.124 source code for libm.a (which was itself based on free code originally developed by Sun Microsystems, Inc.), so this library is free software covered by the GNU Library General Public License.
