[R] birthday problem (factorial limit)

[Jörg Groß]

Hi,

I tried to calculate the formula for the birthday problem
(the probability that at least two people out of a group of n people  
share the same birthday)

But the factorial-function allows me only to calculate factorials up  
to 170.


So is there a way to push that limit?

to solve this formula:

(factorial(365) / factorial((365-23))) / (365^23)

(n=23)
