CalculaThreeDS is a scientific calculator homebrew written in C++17 for the 3DS.

User guide

The interface is split between 4 parts:

  • Memory on the top screen, up to 12 calculations can be remembered and copied back to the working board.
  • Input area on the bottom screen, where what you type will appear, using a custom pretty-printing system (freely sized fractions, exponents, and square roots).
  • Keyboard panel selector on a black background.
  • An intuitive touch keyboard with all the inputs you will ever need.

The touch keyboard consists of 3 different panels:

  • Basic input, for operations and digits.
  • Functions (don't forget to put parentheses after).
  • User variables (10 of them) and user functions (3, TODO) with an assignment (arrow) sign that can appear anywhere in a calculation.

Controls

D-Pad or Touchscreen - Move the cursor after you typed things out

B or Delete Key - Remove content

A or Equals key - Launch the calculation
