The gamma function via interpolation
http://www.vertexdoc.com/doc/the-gamma-function-via-interpolation Web26 Mar 2024 · The gamma function satisfies Γ ( x + 1) = x Γ ( x ), and so you can evaluate the function anywhere if you can evaluate it on an interval of length 1. For example, the next section gives an approximation on the interval [2, 3]. We could reduce calculating Γ (4.2) to a problem on that interval by Γ (4.2) = 3.2 Γ (3.2) = 3.2 × 2.2 Γ (2.2)
