Check out an RPN calculator for different projects on your Mac. Enable the mode for always staying on top of active windows and switch between environments, applications, and processes while maintaining awareness of numerical data and the required calculations.
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.
v2.7 [Apr 17, 2013]
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.
