Overview

Adds an RPN calculator as a browser action button.

This extension adds a convenient reverse Polish notation (RPN) calculator as a browser action button. Also called postfix, RPN calculators take their operators after the operands. For example, to get the sum of two and three on a normal calculator, you would hit "2 + 3 =". On an RPN calculator, you would hit "2 Enter 3 +". In general, RPN calculators require fewer keystrokes over a series of extended operations. It may seem strange at first, but once you get used to it, you'll never go back. HP made a series of extremely popular RPN calculators back in the 1970's and 1980's Known Issues: 1) Calculator doesn't automatically get focus when displayed. 2) Keyboard only. Clicking on keys and commands doesn't work.

This is just the thing I needed! I use it when grading PDF documents in Canvas. I have been an HP calculator user from all the way back when HP was a good company. I had been using my trust 48GX for this, but it's overkill for adding up grades. It's much more convenient to have RPN entry directly in my browser, and this hits the sweet spot of the functions I need vs what is easy to use via keyboard. I really like the onscreen reference too!
