The estimation of pi to over 22 trillion digits was achieved by Peter Trueb in November 2016, who used a personal computer to reach 22,459,157,718,361 digits.
To Professor Yasumasa Kanada, however, pi is an obsession. Kanada and a team of researchers set a new world record by calculating the value of pi to 1.24 trillion places, project team member Makoto Kudo said yesterday. The previous record, set by Kanada in 1999, was 206.158 billion places.
Since Archimedes was one of the first persons (around 200 BCE) to suggest a rational approximation of 22/7 for Ų, the number is sometimes referred to as Archimedes constant.
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 record-setting achievement was documented in a feature video released by the Linus Tech Tips YouTube channel, giving viewers a behind-the-scenes look at the project and revealing the final digit of the record-setting calculation: spoiler alert…the 300 trillionth digit of Pi is 5.
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.
Haraguchi holds the current unofficial world record for reciting 100,000 digits of pi 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 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.
In this final line we have found 3.1416 is between 355/113 and 22/7. And this is where we have the fraction 355/113 is approximately equal to π! (Note this algorithm was based on an approximate value 3.1416 for π, and we got 355/113 < 3.1416 < 22/7.
The 8,346th digit of Pi is 5.
pi has infinite digits, so there has never been a 100% accurate calculation with a circle and there never will be.
Pi in Nature and Science
Pi shows up in unexpected places in the natural world. The structure of spirals in seashells and galaxies, the shapes of rivers, and the frequencies of musical notes all have connections to pi. Even the shapes of atoms and molecular structures reflect pi-related principles.
pi = 3.1415926535 8979323846 2643383279 5028841971 6939937510 5820974944 5923078164 0628620899 8628034825 3421170679 8214808651 3282306647 0938446095 5058223172 5359408128 4811174502 8410270193 8521105559 6446229489 5493038196 4428810975 6659334461 2847564823 3786783165 2712019091 4564856692 3460348610 4543266482 ...
After successfully breaking the speed record for calculating pi to 100 trillion digits last year, the team at StorageReview has taken it up a notch, revealing all the numbers of Pi up to 105 trillion digits! Spoiler: the 105 trillionth digit of Pi is 6!
The Two Quadrillionth Bit of Pi is 0! Distributed Computation of Pi with Apache Hadoop.
The Feynman point is the name given to the position in the decimal expansion of π where a sequence of six consecutive nines first appears. It is named after the physicist Richard Feynman, who allegedly joked that he would like to memorize the digits of pi up to that point and then say “and so on” as if π.
This sequence does not extend above 52 because it is, an untouchable number, since it is never the sum of proper divisors of any number. It is the first untouchable number larger than 2 and 5.
Newton's method, when applied to the integration of (1 + X)^(-1/2) from 0 to 1/2, allowed him to calculate Pi/4. By rearranging this equation, he could derive an approximate value for Pi itself.
What's after trillion? The next number after trillion is quadrillion, or a 1 with 15 zeros after it: 1,000,000,000,000,000. Knowing the names of large numbers can be useful if you're working with extremely large values or doing higher-level mathematics.
You may recognise Pi as 3.14159265358979323846264338327950288419716939937510... etc. The value of Pi here is taken from Scott Hemphill's computed value. The first 1000000 decimal places contain: 99959 0s, 99758 1s, 100026 2s, 100229 3s, 100230 4s, 100359 5s, 99548 6s, 99800 7s, 99985 8s and 100106 9s.
Recently, the record was broken yet again on November 23rd, 2025 with 314 trillion digits of pi. This was done through the usage of the algorithm on y-cruncher.
Twenty-five-year-old Rajveer Meena, a native of Morchala village of Sawaimadhopur district in Rajasthan on Saturday was able to memorise 70,000 digits of the mathematical value of Pi.
On 14 August 2021, a team (DAViS) at the University of Applied Sciences of the Grisons announced completion of the computation of π to 62.8 (approximately 20π) trillion digits.
François Viète discovered the first infinite product for π in the 16th century built from an infinite sequence of nested square roots of 2. François Viète discovered the first infinite product for π in the 16th century built from an infinite sequence of nested square roots of 2.
