How it works
Everything in the standard calculator, plus trigonometry, inverse functions, logarithms, powers, roots, absolute value and factorials. Switch between degrees and radians. Expressions are parsed safely — nothing is executed as code.
- sin(30) = 0.5 (°)
- 2^3^2 = 512
- 5! = 120
- √(16) + ln(e) = 5
