I know they discovered eight consecutive 8's, but this is old news. Perhaps they have broken the record since then.


There are 13 consecutive 8’s. Every other digit has a maximum span of 12.

Some pi statistics here: https://bellard.org/pi/pi2700e9/pidigits.html

Shows thirteen 8s as the longest consecutive streak, starting at Pi digit 2164164669332.

Wasn’t there something about a string of zeros in Pi at the end of the Carl Sagan book Contact that the protagonist used to argue for the existence of a higher power?

All this math talk is making me heady. How about giving actual Pies some love? Lots of restaurants are selling pizza pies and normal pies for cheap! :D I got a .50 pizza slice today! Yum! :D

so I did. Tell me I didn't click on this post anyway. But I did.

With very little computation, I was able to generate pi to the same precision as Excel.

Continued fraction convergents are an even faster method. But, I had not seen your method before ... curious.

In thinking about this more, I calculate about a 96% chance there are at least 14 consecutive equal digits in 31.4 trillions digits, somewhere.

"PI" is conjectured to be a normal number, which is a number that has all integers appearing somewhere in its decimal expansion according to its expected frequency. Aside from PI being transcendental, almost nothing is known about its decimal expansion.

Google has broken the word record by calculating Pi to 31.4 trillion digits

Some more interesting facts about this.

They used the Chudnovsky algorithm

And the current technological bottleneck to calculating more digits faster is not processor speed, but storage bandwidth:

If it is a real number, how would we know if we reached the end when calculating a huge number of digits? Not sure if that question makes sense or not.

I applaud you for not rounding pi up to 3.141592654.
