Check out (7).
AAAIAIAIAGH!!! INTEGRALS SCARY!!!! AIGH!!
Peace,

Well I am always full of s*
I had to teach this stuff at one point to a bunch of engineering students who kept asking "why do we have to learn this". Lots of fun

Wakeup in the morning and kick the day in the teeth!! Or something like that.
"i don't want to write leak free code or most efficient code, like others traditional (so called expert) coders do."

Really the gamma function is a definite integral. But one thing is the factorial of a number and other thing the Gamma function of a number. And yes, for positive integers they are almost the same.
Gamma(x+1)=x!

?
The factorial of any complex number except for negative integers
IS defined. I for one do not argue with definitions. Instead I try to understand why they are useful.
Let me tell you that extensions of the familiar real valued functions with real domian into the complex plane is very useful.
Another example is the complex exponential which is the most important function in the universe.

I will not argue about this. I think this has gone off topic.

(Taking the piss) What's there to argue about?
n! is defined as Gamma(n + 1) for all complex numbers > 0. For positive integers, n! is also defined as n * n-1 * n-2 * ... * 3 * 2.
And BTW, you were the one who asked for a definition from souldog, and now that you've got it, you're unhappy and the thread is 'off-topic'? Sheesh dude.

I didn't mean this as an arguement. I was simply trying to point out the correct way to approach mathematics.

Not, I'm not unhappy.

OK, I wanted to say that the original question is about n! with integers, then there is no need to discuss in this thread about the "extended" factorial function. Only that!

I never heard about a complex factorial.
Can you provide a definition? for example (a+bi)! with b!=0?
... and later ...

Guys, what about letting this thread die in peace, without flamewar, hummm? Please?

Yeah, sorry, my fault - I shouldn't be such a boob. Like I said, I'm grumpy today. Stupid COM objects...
