C++ Mathematical Expression Library

The C++ Mathematical Expression Library (ExprTk) is a simple to use, easy to integrate and extremely efficient and fast mathematical expression parsing and evaluation engine. The parsing engine supports various kinds of functional, logic processing semantics and is very easily extendible.
