A scientific calculator based on the classic HP 41C.

Full HP 41C emulator:

- 64 memory registers.
- Automatic save and load of state.
- No modules support.
- 'ON' only active on 'longtouch' to avoid mistakes.
- Master clear supported (use 'press back' menu when calculator is off then press 'ON', then press 'back' to release it).
- No sound

Avoid checking 'force gpu rendering' in developer option in android 4.x prefs, this leads to graphic problems.
On S5 devices, long press the right hardware button to get the menu.

To have more features, get go41cx (sound, modules, printer, ...) for tablet see go41cxt (wand, debug ...)
