Math Calculator

Calculate everywhere on your wrist with a scientific calculator available for both physical button and touchscreen devices. This full-featured calculator can be useful when shopping, doing math homework, changing currency etc. There are three evaluation modes: Traditional/Postfix/Prefix. An expression can expand into multiple lines. IMPORTANT: EXIT can be found in the menu (press and hold UP/MENU button)!!! #### USAGE ON NON-TOUCHSCREEN DEVICES #### - Menu (press and hold up button): access to Exit, switch between Traditional, Prefix and Postfix/RPN modes. - Back button: access to the math operations, math constants, delete, and clear. - Start button: add new digit to the last number or add a new number to the expression. - Up/down button: rotate between digits and decimal point. #### USAGE ON TOUCHSCREEN DEVICES #### - Swipe up/down: rotate between digits and decimal point. - Back: usually exits the app (depending on device). - Tap on the top label (Traditional/Prefix/Postfix): access to Exit, switch between Traditional, Prefix and Postfix modes. - Tap on letter O: access to the math operations, math constants, delete and clear. - Tap on letter D: add new digit to the last number or add a new number to the expression. - Any keypress: delete. #### NOTES #### Idea for the user interface was taken from https://github.com/rvk/rpncalc. In Traditional mode `log` is implemented as a binary function e.g. 2log1024 = 10. Floating-point calculations are accurate up to 5 decimal places. On some Edge cycling computers, the design may look odd. The stack-based RPN is limited to 5 numbers.

!!! Important: Press and hold UP/MENU to EXIT the app !!! [v2.5.0] New devices supported. [v2.4.8] Pi value fixed from 3.141565 to 3.141592 [v2.4.7] Supports Forerunner 255 and its variants (s/music) [v2.4.6] Swipe to the right now immediately exits the app. (thanks to Nick) [v2.4.5] Adds swap op. to RPN stack, fenix 7 type up-down buttons can now increase/decrease digits. (thanks to Nick) [v2.4.3 & v2.4.4] Bug fixes. [v2.4.2] Previous digit entry restored, new stack-based RPN, support for fenix 7 and epix (gen 2), bug fixes. [v2.4.1] Touchscreen key-press serves as delete function, new digit entry. [v2.4] Fixes tap issues for touchscreen devices. [v2.3] There is now support for touchscreen devices, Venu, Vivoactive 3&4, Marq, Edge. Please note that I don't possess a touchscreen device, so I had no way of testing it thoroughly.
