7817924264. So now, according to scientists from the University of Graubünden, the last ten known digits of this arguably most famous mathematical constant are given.

The calculation was made possible by a high-performance computer, which spent 108 days and nine hours with it. According to the Euronews server, it was about 3.5 times faster in its calculation than in last year’s US record (the reported 50 trillion).

Chur-based colleges have announced the results of their work in the Guinness Book of Records. The full text of the issue will not be published until registration in the disc collection is complete.

Pi is a number that indicates the ratio of the circumference of a circle to its diameter. Its first digit, 3.14, is well known worldwide, but the number is infinitely large. Extending a known sequence of digits to pi is very difficult because the number does not follow any given model.

Pi is used in engineering, physics, or space exploration because its value can be used to calculate waves, circles, and cylinders.

The search for a larger edition of the issue is a long-term concern for mathematicians. In the real world, however, its extension is not widely used. The US National Aeronautics and Space Administration (NASA) uses a 15-digit pi in its calculations.
