Even more pi in the sky: Calculating 100 trillion digits of pi on Google Cloud.
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.
The agency's Jet Propulsion Laboratory said its highest accuracy calculation — which is used for interplanetary navigation — is 3.141592653589793.
StorageReview Calculated 100 Trillion Digits of Pi in 54 days, Besting Google Cloud. Pi represents the ratio of a circle's circumference to its diameter, and it has an infinite number of decimal digits that never repeat or end.
In a brand new mathematical record, the value of pi has been calculated to 62.8 trillion digits. This feat was achieved by swiss researchers who made a computer work for 108 days to get to this value. Their approximation beat the previous world record of 50tn decimal places, and was calculated 3.5 times as quickly.
Akira Haraguchi (原口 證, Haraguchi Akira) (born 1946, Miyagi Prefecture), is a retired Japanese engineer known for memorizing and reciting digits of pi.
3.14159265358979323846264338327950288419716939937510 etc. Before you click remember - it's a byte a digit! 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.
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!
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.
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.
NASA only uses around 15 digits of pi in its calculations for sending rockets into space. To get an atom-precise measurement of the universe, you would only need around 40. So computing trillions of digits of pi is mostly about showing off computer power.
"Pi has been known for centuries to a precision of several hundred digits. Even in the most precise calculations in science and engineering, a few dozen digits are enough."

This poster shows some of the ways NASA scientists and engineers use the mathematical constant pi (3.14) and includes common pi formulas.
“The ratio of a circle's circumference to its diameter is always the same: 3.14159… and on and on (literally!) forever. This irrational number, pi, has an infinite number of digits, so we'll never figure out its exact value no matter how close we seem to get.
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.
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.
Value of Pi (π) in Fractions
The pi value in fraction is 22/7. It is known that pi is an irrational number which means that the digits after the decimal point are never-ending and being a non-terminating value. Therefore, 22/7 is used for everyday calculations.
But in 1768, the Swiss mathematician Johann Lambert revealed the remarkable fact that it's impossible to use any such fractions to pin down the precise value of Pi, as it just goes on forever.
: The billionth digit of pi is 9.”
The Pi Network's future depends on the process of its transition from the Testnet to Mainnet operations and the adoption of the app in the Pi Network ecosystem. The future predictions for the Pi network might show an extremely impressive potential.
However, pi has no value as of 6 April 2023, more than four years after it was initially launched. It cannot be sold on any exchange. It does not yet exist on a live blockchain. It has no wallet.
Simply put, pi is weird. Mathematicians call it a "transcendental number" because its value cannot be calculated by any combination of addition, subtraction, multiplication, division, and square root extraction.
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.
The first calculation of π was done by Archimedes of Syracuse (287–212 BC), one of the greatest mathematicians of the ancient world.
