Returns the natural log of the GAMMA function of X. The GAMMA function is a generalization of the factorial function that works on all positive values of X. For an integer N the factorial of N is equal to the GAMMA function of N+1. The GAMMA LN function is very useful for computing combinitorial factors.
Example
EXP(GAMMA LN(4)) is equal to 6 or 3 factorial
| EXP(GAMMA LN(things to pick from+1) - |
| GAMMA LN(things to pick from-things picked+1) - |
| GAMMA LN(things picked+1)) is the number of combinations possible |
| Units: | GAMMA LN(dmnl) -> dmnl |
The input to the GAMMA LN function must be dimensionless.
