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

User guide

Interface

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.
• Touch keyboard with all the inputs you will ever need.

Touch keyboard

3 panels are available for the intuitive touch keyboard:

• 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
