About this tool
IconVault's Math Evaluator computes math expressions with a hand-written parser, never eval() or Function(), so it is safe by design. Type full expressions with parentheses, powers, modulo, and functions like sin, cos, tan, sqrt, log and ln, plus the constants pi and e, and get an instant result.
An on-screen keypad with clear and delete keys makes quick entry easy, and with no server round trip everything runs fully in your browser. It is free to try (repeated use may ask for Pro).
