~4, I didn't think there WAS a highest number. I knew high numbers existed, but due to the nature of mathematics, you can't imagine a real, highest number. That's what I was tought. I still don't know why.
~3 I thought it was qintilions tho.
pi also does not have the most digits.
pi, while it does have infinite digits, still is again, one of the smallest numbers in terms of digits.
Technically, the largest digit holder would be Omega Ometated to pi. (Ometation / Ometated: Omega in exponentation terms, meaning you raise omega to omega, omega times, omega times (Basically, infinity^infinity^infinity... For the rest of infinity))
Actually, that's not infinity. That exists within one though.
Aleph Null, the smallest of infinities, exists to contain all physically countable numbers.
Then there's the powerset of Aleph Null, all sets of numbers creatable with all possible countable numbers.
Then there's omega. The thing after aleph null.
Then omega^Aleph Null.
Then Omega^Omega.
Then Omega^^Omega.
And so on.
There are infinite infinities.
