Lanczos approximation to the Gamma function. It is related to the Gamma function by the following equation $Γ (x) = \sqrt{2 π} \frac{(g + x + \frac{1}{2})^{x + \frac{1}{2}} e^{- (g + x + \frac{1}{2})} lanczos (x)}{x}$ where $g$ is the Lanczos constant. See equations (1) through (5), and Paul Godfrey's Note on the computation of the convergent Lanczos complex Gamma approximation.
