Coincidentally, I just did a calculation a few weeks ago whose answer was 10 ^ 3200.
Further coincidence: a friend yesterday bragged to me about how great Mathematica
is. Here is his note, sorry the context will be sensless to you but observe the

I hjust spent 45 minutes with mathematica. I managed to compute the
actual and approximated sums for N=1000 to N=20000
(20 digits accuray -- these numbers go to 10^-8000!). The ratio
real/approximation is 1+10^-7 , meaning we have a very simple and good
...so sometimes numbers just get really really big. Annoying little devils.
