Angles are in radians (e.g. use sin(rad(30)) for degrees). Supports + − × ÷, ^, parentheses, and functions like sqrt, ln, log, sin, cos, tan, fact, and constants π and e.
How to use the scientific calculator
Type an expression or tap the keypad. The result updates live as you type. You can
nest parentheses and combine functions freely — for example
sqrt(3^2 + 4^2) returns 5, and log(1000) returns 3.
Supported functions and operators
- Arithmetic: + − × ÷, exponent
^, parentheses - Roots and logs:
sqrt,cbrt,ln,log(base 10),log2 - Trigonometry (radians):

Working in degrees
Trigonometric functions expect radians. To work in degrees, wrap the angle with
rad() — for example sin(rad(30)) equals 0.5. Use
deg() to convert a radian result back to degrees.
