Conversation. PSA: "69" first shows up in the 42nd and 43rd digits of pi. It occurs 98 times in the first 10,000 digits.
The string 123456789 did not occur in the first 200000000 digits of pi after position 0. (Sorry! Don't give up, Pi contains lots of other cool strings.)
The string 42069 occurs at position 250301. This string occurs 1996 times in the first 200M digits of Pi. counting from the first digit after the decimal point.
The last digit of the number above is the 68th decimal of Pi. As you can see, the 68th decimal of Pi is 1. However, Pi starts with 3 which is also a digit. Thus, if you start at 3, then the sixty-eighth digit of Pi is 8.
Humans have now calculated the never-ending number to 31,415,926,535,897 (get it?) — about 31.4 trillion — decimal places. It's a Pi Day miracle! Previously, we published a story about humans' pursuit of pi's infinite string of digits.
The 100-trillionth decimal place of π (pi) is 0. A few months ago, on an average Tuesday morning in March, I sat down with my coffee to check on the program that had been running a calculation from my home office for 157 days. It was finally time — I was going to be the first and only person to ever see the number.
But did you know those post-decimal numbers continue infinitely? Pi is an irrational number, which means it cannot be represented as a simple fraction, and those numbers cannot be represented as terminating or repeating decimals. Therefore, the digits of pi go on forever in a seemingly random sequence.
As you can see, the 69th decimal of Pi is 6.
Last time it took pi to 31.4 trillion digits. The last 100 digits of the 100 trillion pi it discovered are: 4658718895 1242883556 4671544483 9873493812 1206904813 2656719174 5255431487 2142102057 7077336434 3095295560.

PI was once thought to be very rare, but now it is considered more common. As PI awareness with physicians continues to grow, more people are being diagnosed. In fact, PI can affect as many as 1 in 1200 people, which is more common than cystic fibrosis.
Pi is an irrational number, which means that it is a real number that cannot be expressed by a simple fraction. That's because pi is what mathematicians call an "infinite decimal" — after the decimal point, the digits go on forever and ever.
The sequence 999999 occurs at decimal 762 (which is sometimes called the Feynman point; Wells 1986, p. 51) and continues as 9999998, which is largest value of any seven digits in the first million decimals.
The number pi is literally infinitely long. But the number 123456 doesn't appear anywhere in the first million digits of pi. It is a bit shocking because if a million digits of pi don't have the sequence 124356, it definitely is the most unique number.
The 31 trillion digits of pi took 25 virtual machines 121 days to calculate. In contrast, the previous record holder, Peter Trueb, used just a single fast computer, albeit one equipped with two dozen 6TB hard drives to handle the huge dataset that was produced.
What is tau (τ) Tau, which is also known as τ, is a mathematical constant that is 2 times π: π = 3.14159265358…
We have known since the 18th century that we will never be able to calculate all the digits of pi because it is an irrational number, one that continues forever without any repeating pattern.
Memorization of pi
Haraguchi holds the current unofficial world record (100,000 digits) in 16 hours, starting at 9:00 a.m. (16:28 GMT) on October 3, 2006. He equaled his previous record of 83,500 digits by nightfall and then continued until stopping with digit number 100,000 at 1:28 a.m. on October 4, 2006.
The number (69420) comes up twice in the first 100,000 decimal digits of π. That is, it comes up twice as often as one would expect/ predict.
It is denoted by the Greek letter “π” and used in mathematics to represent a constant, approximately equal to 3.14159. Pi was originally discovered as the constant equal to the ratio of the circumference of a circle to its diameter. The number has been calculated to over one trillion digits beyond its decimal point.
Six nines in pi - also known as Feynman point - is a famous mathematical coincidence. It corresponds to a sequence of six 9's which occurs in the decimal representation of the number π starting at the 762nd decimal place.
It's not possible that the decimal expansion of π is finite and we just weren't patient enough. π is an irrational number, and irrational numbers have non-terminating, non-repeating decimal expansions.
Because π is irrational, it has an infinite number of digits in its decimal representation, and does not settle into an infinitely repeating pattern of digits.
