Math Parser

[Matthew Butler]

Hey All,

I was wondering if anyone has a Math Parser bean or knows of one. I'm
looking for a bean that I can send an expression like "10+90*(87/5)" and it
will return the correct expression. Any help would be appreciated.

Thanks,

If you want massive overkill, there are Java implementations of
interpreters for a number of languages, including ECMAscript (the
standardized version of Javascript)...

Try looking on Alphaworks, under beans. I believe there's
one there, but I'm not sure.

There is a JbcParser library for Java. There are math parsers for many languages at http://www.mathparsers.com/ C++, Java, Objective C, C#, Delphi, COM (vb 6 anyone?) are all covered by a suite of math parser libraries. Most of them support strictly mathematical formulas in the expression to parse. C# version supports strings in the expression as well. Users can define their own variables and user defined functions to use in the expressions. The variables need not be defined ahead of time too. There is a callback you can register to provide any variable value at runtime if pre-defining all variables is not possible.
