Title: RPNCalc
Post by: Reo on April 11, 2012, 02:40:11 am

I've yearned for an RPN calculator on the nspire so I can train myself in using it, so I created one in LUA.
In the default mode, it has 16 registers and has access to most common operations, and it also saves properly.
You can read more about what RPN is on Wikipedia. There's also a bit more about the app, as well as sample expressions in the readme.
If you want, you can copy and paste the script into other problems from both the calculator and the student software.

I'm pretty sure this is compatible with all nspires, including clickpads. If not, let me know.

This sounds nice. I wonder if it wouldn't be better to have all 16 boxes in one page, though? After all, the screen is a decent size so it shouldn't be too small. Or maybe allow the option to do so, like in the top-right screenshot, but full screen?

I probably won't use it much except to mess around, though, as I am not familiar with RPN.
