My birthday (in MMDDYYYY format) appears 23 times, within the first two billion digits of pi.

It also appears 17 times, within the first two billion digits of both e and √2.

How does your birthday string compare?

π, e, √2 - all related to your birth(day) - I knew you were born irrational!!!

IRRATIONAL - I mean TRANSCENDENTALLY irrational - very hard to deal with!!

I wore my mouse out by clicking "next" and obtained 21, 16 & 22 times. Total 59, so I have the highest total so far, woo hoo! Lex & Otis only got total 57, come on put some effort in :p

I guess the best number simile to describe me is "just odd" ;) Here's a list of x, and the probability that the number of matches (for 8 digits within 2 billion random digits) is less than or equal to x:-
10 0.011
11 0.021
12 0.039
13 0.066
14 0.105
15 0.157
16 0.221
17 0.297
18 0.381
19 0.470
20 0.559
21 0.644
22 0.721
23 0.787
24 0.843
25 0.888

Okay, but first give me 40 terabytes, so I can download the 50-billion-digit version.

:sneaky:
And I thought 2 billion was a lot!

I just found a slice of rounded pi (3141592654) within sqrt(2). At the 497,716,922nd digit!
