Thank you very much! The usage of your expression parser is the same to what 
DeskCalc used to use. So it was very easy to add your parser to DeskCalc. 
What I especially like is that stuff like sin() is already supported by it. 
(Though I need to add that to DeskCalc yet...)

If nobody minds, I can put DeskCalc into the Haiku tree, after cleaning it up 
some more.

Daniel, may I change the license stated in your code to MIT?

Best regards,
