Jep.Net 1.0 Release | Jun. 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. 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.
For more information visit the Jep page.
Jep 3.2 Release | Feb. 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 Extensions
Jep addons
Jep Extensions is a
set of extensions to jep providing: differentiation and symbolic operations;
a type system with matrices, rational numbers, and custom types;
very fast evaluation for pre-compiled expressions;
limited structured programming with for and while loops;
statistical functions and distributions.
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.
GWTJep
Jep for javascript
A version of Jep for use with javascript GWTJep
is a cross-compiled using Googles Google Web Toolkit.
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.
