This is a four function calculator ( +, -, / and *) component for D2.  
I haven't tested in D1, but it should work just fine.
Install it.  Drop it in a form and you got a caculator.

It is free for the taking.  I'm not responsible for any ERROR!!!

Do what ever you want with it.  Modify it, sell it... :)

If need help or want feature add to it, email to: 

I don't have time to finish the keyboard equivalent for those buttons,
so if you want those feature and don't want to extend it yourself,
drop me a note.
