Syntax

Visual Basic (Declaration)
Public Shared Function Gamma ( _
	x As Double _
) As Double
C#
public static double Gamma (
	double x
)
Visual C++
public:
static double Gamma (
	double x
)

Parameters

x
System.Double
A real number.

Return Value

The value of the Gamma function for x

Remarks

The Gamma function is a generalization to real numbers of the factorial of an integer. If x is a positive integer, then the following equality holds: 
Combinatorics.Factorial(x) = GammaFunctions.Gamma(x+1)

The formal definition of the Gamma function is as follows:
