Jep.Net 1.0 Release | Jun. 15, 2009
We are proud to announce the release of Jep.Net v1.0! This is a careful, hand-crafted port of the 3.2 version of Jep to the .Net framework. This product represents a perfect meld of .Net innovations and years of development and refinement of the original Jep parser and evaluator.

For more information and a trial download visit the Jep.Net page.

Jep 3.3 Release | Nov. 30, 2008
The newest Jep release of is now available for download! We have drastically improved evaluation speeds for real-number calculations, added additional functions and enhanced the operator table functionality.

Jep 3.2 Release | Feb. 14, 2008
A new release of Jep is now available! We made a bunch of improvements to the configurable parser component, making it even more powerful than before. Additionally you can now analyse parsed expressions, parse multiple expressions separated by semi-colons, and much more.

Jep Java

Java Math Expression Parser

Jep Java is a library for parsing and evaluating mathematical expressions. With this API you can allow your users to enter an arbitrary formula as a string, and instantly evaluate it.

With over 500 downloads per month, the number of Jep users is rapidly growing. Have a look at the Jep example applets as well as AutoAbacus, to see Jep in action!

Jep.Net

Math Expression Parser for .Net

Just like Jep Java, Jep.Net is a library for parsing and evaluating mathematical expressions except as a .Net component.

Be sure to check out the trial version which includes a number of excellent demonstrations of how this library could be put to use in your next project. You will be impressed with the extendible architecture, ease-of-use, and speed of Jep.Net.

AutoAbacus

Equation solving library

AutoAbacus is a powerful equation solving library that finds solutions to equation sets with a snap. Equations are passed to AutoAbacus as text, while the program attempts to find a solution that satisfies all constraints.
