Gamma

java.lang.Object
- org.apache.commons.numbers.gamma.Gamma

```
public final class Gamma
extends java.lang.Object
```
Gamma function \( \Gamma(x) \).
The gamma function can be seen to extend the factorial function to cover real and complex numbers, but with its argument shifted by -1. This implementation supports real numbers.
This code has been adapted from:
- The Boost c++ implementation <boost/math/special_functions/gamma.hpp>.
- The NSWC Library of Mathematics Subroutines double precision implementation, DGAMMA.
