A real number. - x
- Type: SystemDouble
A real number.
Return Value
Type:
DoubleThe incomplete Gamma function
for
x
The Gamma function is a generalization to
real numbers of the factorial of an integer.
If x is an integer, then the following
equality holds:
\1
The term incomplete here refers to the fact
that the integral in the definition
of the Gamma function is taken from
x onwards instead of from 0.
