What's New
The application now stays running when the window is closed. This means that if you use the calculator and then close the window to do something else, you can go back to the calculator without having to relaunch the entire app.
App Description
This RPN calculator always stays on top, whether it's the active application or not. It's very handy when you need to go back and forth between the calculator and another window, but don't want the calculator to get lost.
The RPN behavior in this app is based on classic HP calculators. All the essential functions for everyday calculation are included. All memory registers are saved when you quit the app.
