How it works & limits

Type an expression or use the keypad. Enter or = saves the result. Multiplication must be explicit: use 2*pi, not 2pi. Powers are right-associative (2^3^2 = 512); −2^2 = −4. Percent is a postfix division by 100, so 100 + 10% = 100.1.

Functions: sin, cos, tan, asin, acos, atan, sqrt, ln (natural), log (base 10), abs, exp, floor, ceil. Trigonometric functions use the selected degrees/radians mode. Factorial accepts integers 0–69. Expressions allow 256 characters, 128 tokens and 32 nested operations; real finite results must be within ±1e100. Calculations use floating-point arithmetic and display 12 significant digits.
