How it works
Type expressions as you would write them: 2(3+4)^2, sin(30), √2, 5!, 15% * 80. Implicit multiplication (2π, 3(4)) and the usual order of operations are supported; powers are right-associative, so 2^3^2 = 2^9. The expression is parsed by KadiTools's own evaluator — it never runs code. Press Enter to calculate, Esc to clear, and use ans for the previous result.
FAQ
Degrees or radians?
Click DEG/RAD to switch. In degrees, sin(30) = 0.5; in radians, sin(π/6) = 0.5.
Why is 0.1 + 0.2 shown as 0.3?
Results are rounded to 12 significant digits to hide floating-point noise like 0.30000000000000004.
