Question: exp(Pi) something

Perhaps someone knows this. So I came across something recently and I can't recall if it was in this forum (which I can't find)

It was a value using some combinations of the constants e and Pi where the answer was very close to a whole number x.99939 or something.  The only thing I can remember is that it was exp(Pi)*...  I thought it was an answer written by Joe Riel where someone would use that to verify if the floating points... well I can't recall. 

Would anyone have an idea?

Please Wait...
