Works great! E.Falk put a great deal of thought into this one. Best I have seen anywhere... He keeps it coming with great updates. Thanks for such an awesome, neat, spectacular app. Some don't work well or fall short. His is better 5 stars.
RPN lives! As 40 year RPN user, this app nails the need. Three calculators in one--12c, a scientific & a basic 4-banger. Complete with classic looks. Good work!
Well done! The best 12c app in the store. Worth every cent.
Excellent Excellent...genuine HP12C replacement!
One darn fine calculator I love this thing. Still great! It has changed my life forever. Ed Falk is geeky great. Buy this and stop messing around with inferior renditions.
Just like my old HP-21 and 19C I love RPN. It's great to have the basic calculator again and the business one. Missed it for 15 years until I found this app.
v2.0 introduces a decimal math library for improved compatibility, precision, and round-off error.
Also adds Portuguese translation and a preferences setting to control how very small numbers are displayed.
