Gammln used in betainv

Hi there!
The most common implementations of Betainv use a function called "Gammln" which uses an array of numbers called COF: (76.180091729471457, 86.505320329416776,24.014098240830911, 1.231739572450155,0.12086509738661, 5.395239384953e06)
If anyone would be so kind as to shed some light on these numbers, e.g. where do they come from and what is their exact purpose in the model, ...or just provide the name of a book which contains this information, I would be most grateful.
best, MJ
