Pi has been calculated to an astonishing 62.8 trillion figures by a team of Swiss scientists who spent 108 days working it up - 3.5 times as fast as the previous record.
The previous record was calculated to 50 trillion figures, and was set in 2020, said experts from Graubuenden University of Applied Sciences in Chur, Switzerland.
Researchers haven't revealed the exact numbers involved in the extra 12.8 trillion digits, as they are waiting on the Guinness Book of Records to certify their achievement, but say the final 10 digits they discovered are '7817924262'.
The number π (pi) is a constant in mathematics that is roughly equal to 3.14159, and is the ratio of a circle's circumference to its diameter.
The previous record of 50 trillion digits was set by Timothy Mullican from the US, who achieved the feat after eight months of processing in January 2020.
**SNIP**
What is mathematically interesting is that pi has no regularity or repetition.
This means that it is impossible to specify pi exactly as a decimal point.
It means you can only get closer and closer to the exact number, never achieving the exact number.
This makes it a 'transcendent' number, according to the Swiss data scientists.

I just round it down to 3.
this is just today’s 5th reverse REPO exceeding
a trillion bucks. new record. /s
My physics teacher told me that 37 digits was enough to create a circle the size of the universe.
That’s a lot of Strawberry-Rhubarb.
They’ll put out a retraction shortly, as they discovered Dr. DippyDoo was looking at the wrong data... that’s the National Debt.
As long as pi is approximate, any calculation using pi is approximate only.
Makes it hard to fit the leftover pi in the fridge.
wonder how much excess carbon was generated for this pretty useless exercise?
Some people need a better hobby.
That’ll help. That old pi calculation used to really mess me up in math class.
Tastes so good, I posted it twice...
Point of order: The term is transcendental, not transcend, number.
The history of π is a fascinating subject, and attempts to calculate pi have contributed to our fundamental understanding of mathematics. The first person to devise a formal and rigorous way of calculating π was Archimedes, who used inscribed and inscribing polygons. Archimedes method allows one to bound pi between two limiting values.
No one improved on Archimedes method until Newton. Newton introduced several innovations, including generalization of the binomial theorem to non-integer powers, and invention of calculus, which enabled him to calculate pi far more efficiently.
There now exists a method for calculating the Nth hexadecimal digit of π. This can serve as a valuable check on long calculations, since they will almost certainly be done as binary numbers before conversion to decimal, so one can easily check a sample of digits along the way to validate the calculations.
And boy...are their index fingers tired!
Back in grade school my twin daughters memorized PI. They were very competitive. One did to 40 something figures, and the other to 50 something. They both got the prize in their class (a slice of pie).
I asked them what the next closest kid had. I think the one class had something in the 20’s, and the other was under 10!
Hmmm, the last 10 digits in my answer came out 7817924261. I’d better check.
