Cross-platform parser
"TCioinaEval is a robust cross-platform mathematical expression evaluator for Delphi 6+ and Kylix 2+ that parses input strings at blazing speed (as much as 9 to 10 times faster than UCalc 2.0, according to numerous tests that Alexei has run) and offers top-notch calculating performance. TCioinaEval includes a huge library of built-in functions and will of course accept user defined functions and constants (a maximum 65535 for the latest version). In addition, TCioinaEval can provide symbolic differentiation of the functions it is asked to evaluate and (unique, in my experience) export its results in Mathematica 4.1 format".
