Return Value

The Gamma function is a generalization of the factorial (see Factorial(Int32)) to arbitrary real values.

For positive integer arguments, this integral evaluates to Γ(n+1)=n!, but it can also be evaluated for non-integer z.

Because Γ(x) grows beyond the largest value that can be represented by a Double at quite moderate values of x, you may find it useful to work with the LogGamma(Double) method, which returns ln(Γ(x)).

To evaluate the Gamma function for a complex argument, use Gamma(Complex).
