I'm evaluating Expr4J for possible inclusion in a project that would require complex math. I'd need a complex data type and implementations for COMPLEX, IMABS, IMAGINARY, IMARGUMENT, etc.

Is anybody working on that? If so, perhaps we could collaborate on it. If not, and if Expr4J looks otherwise suitable for my project, I'll consider creating a patch.

I see that the project exists at https://github.com/ccp999/Expr4j, so is that where I should work on the update? The repository seems to have the same source as sourceforge, except that it also includes some test programs.
