JEP, Java library for parsing and evaluating mathematical expressions is available in new release Jep 3.2. This package allows users to enter an arbitrary formula as a string and evaluate it. JEP supports user defined variables, constants, and functions. A number of common mathematical functions and constants are also included.

The new release of Jep is available with improvements to the configurable parser component including parsed expressions, parse multiple expressions separated by semi-colons, and much more. A trial version of Jep is available for download.

Changes from Jep 3.1 to 3.2 include added support for expression tree analysis using TreeAnalyser, fixed errors in the documentation of the default configuration and improved operator table.
