What is this tool?

Scientific calculators add trigonometry, logarithms, exponents, and memory beyond basic arithmetic. This implementation runs locally, supports degree/radian modes, and accepts keyboard input for faster entry.

How to use it

  1. Tap buttons or use your keyboard (digits, + − * /, Enter, Esc).
  2. Switch DEG/RAD before using trig functions.
  3. Use M+/M−/MR/MC for memory, and C to clear.
