![]() ![]() No one can yet rule out the possibility that at some point beyond the range of current computations of pi’s value, its decimal digits revert to a string constrained to, say, only the digits 1 and 0. swiss researchers have said they calculated the mathematical constant pi to a new worldrecord level of exactitude hitting 628 trillion figures using a. It’s not even firmly established that all digits appear infinitely often, for example. 'The calculation took 108 days and nine hours' using a supercomputer, the Graubuenden University of Applied Sciences said in a statement. That’s still not enough to settle questions about the distribution and apparent randomness of pi’s digits. (Igor Sokalski/Getty Images) Swiss researchers said Monday they had calculated the mathematical constant pi to a new world-record level of exactitude, hitting 62.8 trillion figures using a supercomputer. ![]() Here are Kanada’s complete results for the first 800 billion digits: Digit It actually occurs 79,999,775,965 times–close the expected value. In other words, you would expect the digit 7 to appear 80 billion times among the first 800 billion digits of pi. The expectation is that each of the digits from 0 to 9 should appear about one-tenth of the time. Kanada has started to analyze the statistical distribution of the digits of pi and posted preliminary results at . In 2021, scientists at the University of Applied Sciences of the Grisons (opens in new tab) brought the total up to 62.8 trillion digits using two AMD Epyc 32-core processors and 1TB of RAM. The 1,241,100,000,000th decimal digit of pi (not counting the initial digit, 3) is 5. Kanada estimates that if the new version of the algorithm had been applied in 1999 to compute 206 billion digits of pi, the total calculation time on the same computer would have been cut from 83 to 38 hours. The new record is enabled by a supercomputer running a specialized algorithm. Improvements in the computer algorithm used for the main calculation also contributed to the feat. Researchers have set a new record for calculating digits of pi: 62.8 trillion decimals. A Swiss research team announced that they used a supercomputer to calculate the pi to 62.8 trillion decimal places This number is far beyond our imagination. The record-breaking value counts 62,831,853,071,796 digits, as confirmed by project leader Thomas Keller and his team on 19 August 2021, adding 12.8 billion new digits to pi. P = 16 arctangent(1/5) – 4 arctangent(1/239).īy using two different formulas, the researchers were able to compare the outputs and certify the calculation’s accuracy. Using a high-performance computer, a team of Swiss researchers have calculated a new most accurate value of pi. The value of pi can then be obtained from the following equation: The current record is held by Yasumasa Kanada and Daisuke Takahashi from the University of Tokyo with 51 billion digits of pi (51,539,600,000 decimal digits to. For instance, you can use the following expression to work out the value of the arctangent of x to any desired number of decimal places just by evaluating the series to a sufficiently large number of terms:Īrctangent( x) = x – x 3/3 + x 5/5 – x 7/7 + x 9/9 –. To calculate the digits of pi, Kanada and his team used formulas involving arctangent relations of pi. ![]()
