JbcParser is a Java library to parse and evaluate mathematical expressions given as strings at runtime. JbcParser source code can be compiled with JDK 5, 6, 7 and 8. The binaries are compiled with JDK 1.5 for backward compatibility. You get the source code and the compiled jar when you buy this parser library.

mathparser.php implements a MathParser class that parses and evaluates math formulas given as strings at runtime. PHP already has an eval() function for similar purposes. However eval() has security problems where a user supplied expression can cause havoc when executed on a web server or elsewhere. bcParserPHP works around this problem by parsing and evaluating the mathematical expression without using eval() function. bcParserPHP is tested with PHP version 5.2.9 and 5.6.8. The library utilizes newer PHP constructs such as classes, constructors, exceptions.

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.
