The .Math 1.01 Beta fixes the known bugs to date. In addition, sensitivity to regional settings (specifically use of the decimal and group separators) is now an option on the EqCompiler class. This was made optional because applications may or may not wish to be sensitive to these settings depending on operational requirements.
The only urgent bug fix is for multi-valued functions that use 3 or more parameters. If a value beyond the 2nd parameter is a negative constant, an exception was previously thrown. This has been corrected and thanks go out to Ruslan Kiskinov for reporting the bug.
Ruslan has also extended the compiler by adding financial functions to the library. These functions are compiled and can be added to the list of available functions at runtime. I'll be adding this as an extension pack shortly and I'd like to say thanks to Ruslan for graciously providing the code.
