Acron RPN Calculator FREE

Try the Acron RPN Calculator before you buy. The free version has the following limitations:
- Answers are always displayed as floating point. For instance, the full version knows that the sin(45) = sqrt(2)/2, but the free version only knows that it is 0.707106...
- Functions that cannot use floating point numbers as input have been disabled. This includes factor, gcd, lcm, factorial, and all of the binary/decimal/hexidecimal integer functions.

poor integration with Android 9 on my Samsung S9. No online edit makes trial pointless.

OMG, this app is awesome! One small feature I miss is the option to disable the full screen mode. Thanks.

Displays algebraic form of your RPN entered expression. Lots of features.

I just tried it out. Very intuitive. I'll give it a little more workout then, if I don't discover any issues I plan to buy the paid version.

This calculator is too good to be true. I showed it to my staff in a training meeting and they fell in love. Someone finally made a calculator that thinks the way we do. The developer is first rate and very responsive. I like it so much that I upgraded to the paid version.

Nearly perfect. I just wish the button layout was customizable. Good enough in any case - Im buying the paid version right now.
