A great addition to my LG G3. I love that the original HP 42S look is an available skin, the only one I use. Print function integration is a major plus. I reported two very minor bugs to the author, both fixed perfectly in a couple of weeks. I never owned a real 42S, but have owned the real 45, 55, 25, 67, 97 and 41C. Love the 42S functionality. Congratulations, Thomas, and keep up the good work!
Best RPN calculator and HP emulator app that I know. I use it almost daily!
Very good RPN calculator. Thank you to the developer.
Very good implementation.
I have had a 25, then a 15C - always loved HP calculators. This follows the trend perfectly.
Changed the RAN and SEED functions to match the behavior of the real HP-42S. The previous implementation used the algorithm from the HP-41C Standard Pac, which produced numbers with only 6 significant digits.
The up/down annunciator (multi-row menu) did not get updated correctly when VARMENU was activated, including in the solver and integrator. Fixed.
The menu icons for Copy, Paste, and Print-Out were displayed too large, overlapping the menu item labels on some devices. Fixed.
Excellent scientific calculator with expressions, fractions, repeating decimals.
This application supports the calculation for simple and complex formulas.
