Like the subject says this is a scientific RPN calculator. This is an early release so there will be bugs.

I think the behavior of the app is mostly right but it will take some real RPN calculator users to verify that things are ok. If they aren't please let me know and try to be as detailed as possible in your bug report.
Most functions work except for:

- FRAC / INT
- FIX / SCI and ENG notations

For those who don't know how an RPN calculator works here's some examples:

Where you'd normally enter 1, +, 2, = you now use: '1 ENTER 2 +'
Where you'd normally enter 2 * (2 + 5) = you can now just use: '2 ENTER 2 ENTER 5 + x'

As you can see you don't need parenthesis on an RPN calculator. WIN!

I put a cap on large integer sizes because JS gets wonky when the numbers get too big. I don't know if there are ways around this and I don't know if it really matters to most people.

The package should install on non-rooted pre's using the SDK install method.

This application is still under development. There's room for some more functions. I welcome suggestions!

Things I'm thinking of:

- choose between LCD style display and regular text for those who don't like the LCD
- graphing (for the further future)
- your suggestions?

I have attached two screenshots and of course the package.

The com.palm.app version is experimental! It has vibrate feedback when touching keys. The nl.i-marco one is the 'stable' release.
