Scientific calculator

Online scientific calculator

Type a math expression and get the result instantly. It supports trigonometric functions, logarithms, roots, powers and the constants π and e, with a degrees/radians toggle. Everything is computed in your browser.

Supported functions

• Operators: + − × ÷ and power ^, with parentheses.
• Trigonometry: sin, cos, tan, asin, acos, atan (in degrees or radians).
• Others: sqrt, ln, log, abs, exp.
• Constants: pi (π) and e.

Examples

sin(30) + 2^3 = 8.5 (in degrees). sqrt(2) ≈ 1.41421. log(1000) = 3. 2*pi ≈ 6.2832.

Frequently asked questions

Degrees or radians? Use the toggle; by default, degrees for trig functions.

Why does it show "—"? The expression is incomplete or has a syntax error.

Does it use eval? No: a custom parser interprets the expression safely, without running code.
