I just need an accurate total. Yes I know what I am asking is a ridiculous question, but I need it answered for some extra credit and I'm sure as hell not going to go through 9,152,052 digits. I'm hoping by some off chance that perhaps some insane individual actually knows this answer.

sdbardwick 2006-03-23 20:56

And you have your answer, along with the totals for all other digits.

I am curious. Who gives "extra credit" merely for counting digits in a
number?????

That is an accurate answer, there are zero zeros in base 2 in the largest prime.

0, 0's in base 2!!!

how many in total in all bases?

Citrix 2006-03-23 23:16

[QUOTE=paulunderwood]how many in total in all bases?[/QUOTE]

00= infinite

Uncwilly 2006-03-23 23:22

[QUOTE=Citrix]00= infinite[/QUOTE]Incorrect. Once you get past the base that is the number itself, you will run out of 0's. Right, Bob?
