About this calculator
Everything runs in your browser. Nothing you type is sent anywhere, and once the page has loaded it keeps working without a connection.
- Keyboard: digits, + - * / ^ ( ) ! %, Enter for equals, Backspace to delete, Esc to clear.
- Percent works like a phone calculator: 200 + 10% = 220, 200 × 10% = 20.
- Results are tidied so 0.1 + 0.2 shows 0.3.
