FAQ
- Is it safe to evaluate expressions entered in this calculator?
- Yes. The calculator uses a custom shunting-yard parser and RPN evaluator written entirely in JavaScript — it never calls eval() or Function() on user input, so arbitrary code execution is impossible.
- What angle unit do sin, cos, and tan use?
- All trigonometric functions (sin, cos, tan) expect angles in radians. To convert degrees to radians, multiply by pi/180 — for example, sin(90*pi/180) gives 1.
- Is my data sent anywhere?
- No. Every calculation runs entirely inside your browser; nothing is uploaded to any server.
