Java Math Expression Evaluator

Java Unified Expression Language is an implementation of the unified expression language (EL) as specified by the JSP 2.1 standard (JSR-245). The javax.el.ExpressionFactory implementation is de.odysseus.el.ExpressionFactoryImpl: // create an expression factory javax.el.ExpressionFactory...

Jep is a Java package for parsing and evaluating mathematical expressions. It currently supports user defined variables, constants, and functions. The open-source Jep project was halted in favor of commercial development of version 3.0 upwards.

RPN is a Perl extension for Reverse Polish Math Expression Evaluation. SYNOPSIS use Math::RPN; $value=rpn(expr...); @array=rpn(expr...); expr... is one or more scalars or lists of scalars which contain RPN expressions. An RPN expression is a series of numbers and/or operators separated...

Inside Kalculator you can write complete math expression which is then evaluated. You can also see the history for expressions already entered. Variables are also supported, so you can type "a = 0x0fc12 23" and then "b = a pi" for example. pi and e are the only vars built in.Around 20 functions...

2E Programming Language (two es, as in ee, or expression evaluator) is a simple algebraic syntax language. It natively supports expressions (composed of operators and operands), and function definitions, and basically nothing else. Therefore, it can be fairly straight-forward to learn (assuming...
