Irrlicht Engine

I'm working on a small project called math tools which provide some basic mathematic functionnality.

I'm looking for ideas, developper interested in such a project...

actual dev status:
interface : GTK 2.6
platform : win32
functions: -base conversion ( decimal<-->selected )
-prime numbers, check and find
-solve linear systems (1 to 26 unknows) [on work]
-finding prime factors [on work]
-graphing equation [idea]

Which kind of math tool do you think of?
Computer algebra (like Mathematica), solving library (like BLAS/ATLAS), or educational tool (like don't know )
Do you plan to use some library for the math optimizations, or do you want to do everything on your own?

a lots of good questions!

I can't answer you about the general orientation.

I'd rather do as much as possible on my own ( it's the best way to learn isn't it? ) but if I fail to implement a function and find an free lib...
