In the value of the number π, determined by the staff of the Graubünden Graduate School, after the decimal point – 62.8 billion digits.
The number of digits in the number π is infinite
Employees of the Graubünden Graduate School of Applied Sciences, Switzerland, have named the most accurate value of the number π for today. It contains 62.8 billion decimal places. The university announced the completion of the calculations on August 16, but the German media drew attention to this news only on the morning of Monday, August 23. It took the study participants less than 140 days to determine this number.
For comparison: the most accurate value of the number π up to this point had “only” 50 billion digits after the decimal point. It took more than 303 days to find it with the help of a special computer program y-cruncher from its operator, American Timothy Mullikan. The result of the calculations was announced by him on January 29, 2020.
According to scientists from the Graubünden Graduate School of Applied Sciences, the point of their research was not to name the most accurate value of the number π, but to find a way to calculate it.
Infinite number π
The number π was known to the ancient Greeks. It is equal to about 3.14 and shows how many times the circumference is greater than its diameter. This is an irrational number, that is, there is no limit to the digits after the decimal point. However, they do not add up to repeating blocks. According to the Swiss scientists, the last yet known digits of the number π look like this: 7817924264.
World π Day is celebrated on March 14th. If you write this date in the American manner, you get: 3.14.
