(Incomplete) Gamma Function (Not in Base Package)

Evaluates the gamma function or the incomplete gamma function, depending on whether you wire a. The default behavior of the VI is to evaluate the complete gamma function. Wire the a input to evaluate the incomplete beta function. Details  

	x is the input argument.
	a is the upper limit of the incomplete gamma function.
	g(x, a) returns the gamma function for x or the incomplete gamma function for x and a if you have wired a.

(Incomplete) Gamma Function Details

The following equation defines the gamma function.

The gamma function is related to the factorial function by the identity (n + 1) = n! for integer n.

The following equation defines the incomplete gamma function for any real number x and the positive real number a for a > 0.

The following illustration shows the incomplete gamma functions with a = 1, 2, 3, and 4 from top to bottom.
