Good to know
Supports sin, cos, tan, sqrt, abs, ln, log (base 10), exp, pi, e, +, −, *, /, ^, % (remainder) and !. Functions require parentheses and multiplication must be explicit. Exponents associate right to left; −2^2 = −4. Angle mode affects trigonometry only. Factorials accept 0–170. Floating-point results use 12 significant digits; expressions are limited to 500 characters and 200 tokens.
