The Math Extension provides access to advanced math functions.

The PalmOS Math extension also requires the inclusion of the MathLib shared library.

Scripts API

All methods except 'About' return a value.  Unless mentioned otherwise, it is assumed that each method returns a floating-point value.  Also, if there is an error detected the method should always return the last value passed to it.

Usage:  Global Method:  [Name of method]

          Private Method:  [Name of extension].[Name of method]

Example of usage:  Global Method:  ABS(x)

                         Private Method:  Extensions(“Math”).About()

ABS(Float)

Returns the absolute value.

About()

A private method that returns the about box of the Math Extension.
