Frequently Asked Questions

What operations are supported?
Basic arithmetic (+, -, *, /, ^, %), trigonometric functions (sin, cos, tan), logarithms (log base 10, ln natural), and constants (pi, e).
Are trig functions in degrees or radians?
Trigonometric functions use radians, matching the JavaScript Math library. Use pi/180 to convert degrees to radians.
Is my expression sent to a server?
