Bernoulli numbers and large factorials

[Tugdual]

Nice job
I checked the values on Wolfram Alpha and you are prettyu close (for the 10 first digits over 500 ;-) ).

The Prime has Bernouilli numbers calculated internally but unfortunately the Bn function is not exposed in the library. So we can use the formula Bernoulli(x) := –x*Zeta(1–x) (Thanks Joe Horn)

I tried it and couldn't calculate B372; the bigger number is B370.
