Math expression applet

[George Staikos]

   If you are looking for a parser and interpreter, we have one in Kst too, 
and it's mostly self-contained.  I recently rewrote it to be much faster, and 
it contains an optimizer that can already do simple refactoring to increase 
performance of consecutive evaluations.  If you already have what you need, 
there's not much value in changing it - these things are easy to write or 
modify, but the optimizer might be of interest.
