Bestcode Math Parser Components parse and evaluate mathematical expressions given as strings at runtime (aka formula parser). The expression can contain predefined or user defined variables and functions. When evaluation is requested, the parser compiles the expression into a parse tree. Further evaluations are made using this tree that represents the expression. The parser can optimize the tree by simplifying branches that evaluate to a constant. Upgrades are free for registered users. The math parser components are available in various versions for different platforms/languages.
