Result
Gamma Function Calculator The Gamma Function Calculator evaluates Γ(x), the continuous extension of the factorial, using the Lanczos approximation. Enter a value of x. — free online calculator.
Formula
- Gamma Function Calculator calculates its result from x. It uses the formula Γ(x) = ∫₀^∞ t^(x−1) e^(−t) dt; Γ(n) = (n − 1)! for positive integers. Change any input to recalculate the result instantly.
- The main inputs are x. Enter them in the units and format shown in the calculator.
- Keep comparable quantities in compatible units whenever the formula combines or compares them.
- Changing any input above recalculates the result with the same calculation engine used by this page.
Example: Gamma Function
- x: 5
Using x = 5, the calculated result is 24.
