JExel is a Java based expression language. It is a non-compiled scripting language parser that can be useful in many different applications. It can handle most basic mathematical and string expressions with the built in operator set fairly easily.

A basic example of use would be: Expression.evaluate("1 + 2 / max(3, 4, 5) - 4").toDouble();. For additional examples and a list of available commands visit the operators page.
