Looking for a great desktop calculator while doing trade runs in Elite Dangerous that doesn't blind you with a white background in a browser? Check out the Free42 site that emulates the HP-42s scientific calculator which is great for Reverse Polish Notation fans. There are links for Windows, Mac, Linux and Android platforms.
RPN is faster and more efficient with complex calculations as you can combine with existing calculations without starting over. Example:
1000 <ENTER> 25 <X> displays 25,000
<ENTER> stores the 25,000 then 0.2 <X> displays 5,000 as in a 20% bonus.
<X:Y> goes back to 25,000 where another calculation can be performed on it.
<ORANGE BUTTON> <CLEAR> <LOG> clears the memory.
<ORANGE BUTTON> <EXIT> toggles power on/off
Once you go RPN you'll never go back!

Note the desktop size is a lot smaller
