Choose degrees or radians before evaluating trigonometry. Multiplication must use *. Expressions are parsed without JavaScript evaluation. Results are finite real numbers; undefined operations show an error.

Supports +, −, ×, ÷, powers, parentheses, pi, e, sin, cos, tan, asin, acos, atan, sqrt, abs, ln, log and exp.

In degree mode, sin(30) = 0.5 and sqrt(3^2 + 4^2) = 5.

Confirm the input dimensions and unit system against your drawing before calculating. Keep full precision during a calculation and round only the final value to suit the measurement or programming requirement. A numerical result does not account for a machine’s complete setup, workholding or control configuration.
