To 39 decimal places, pi is 3.141592653589793238462643383279502884197. Pi is an irrational number, which means it is not equal to the ratio of any two whole numbers. Its digits do not repeat.
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.
For most calculations, NASA uses 15 digits: 3.141592653589793.
Q. The value of π upto 50 decimal places is given below : 3.14159265358979323846264338327950288419716939937510 From this information prepare an ungrouped frequency distribution table of digits appearing after the decimal point.
The first 15 digits of the never-ending number are: 3.14159265358979. Celebrants around the world honor the day in a myriad of wacky ways, including using actual pies to try to calculate the number 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.
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.
The mathematical pi is defined as “the ratio of the circumference of a circle to its diameter.” It's also known as Archimedes' Constant, after the ancient Greek mathematician of the same name, who, in addition to coming up with an algorithm for calculating pi, also invented an early type of irrigation pump called the ...
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.
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.

This poster shows some of the ways NASA scientists and engineers use the mathematical constant pi (3.14) and includes common pi formulas.
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.
10^7 * 3.141592653589793238462643383… = 31415926.
That's because if you measure the distance around a circle's outside (the circumference) and then the distance across it (the diameter), pi is the circumference divided by the diameter. So anytime you're dealing with circles, it seems quite logical that the number pi could show up.
Pi is the English spelling of the sixteenth letter of the Greek alphabet.
“He used it because the Greek letter Pi corresponds with the letter 'P'… and pi is about the perimeter of the circle.”
The first calculation of π was done by Archimedes of Syracuse (287–212 BC), one of the greatest mathematicians of the ancient world.
But in the end, it was Kondo's persistence that paid off. For his efforts he will be forever known (in the annals of science, and probably the Guinness Book of World Records) as the man who calculated the ten trillionth digit of pi. It's 5.
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.
In the endless pursuit of Pi's post-decimal values, most couldn't get farther than Rajveer Meena — who memorised and recited an unfathomable 70,000 digits in about 10 hours. Rajveer Meena memorised and recited Pi up to 70,000 decimal places while blindfolded. He achieved the feat at VIT in Vellore, India, in 2015.
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.
What is tau (τ) Tau, which is also known as τ, is a mathematical constant that is 2 times π: π = 3.14159265358…
Today, we keep adding digits to pi for two reasons: to avoid any rounding error, and use the computation as a benchmark for high-performance computers. "The 62.8 trillion digits of pi are only a side effect of testing and benchmarking our new computing infrastructure," explained Keller.
