![]() ![]() This time around, the calculation ran for 157 days, 23 hours, 31 minutes and 7.651 seconds, meaning the computers were running more than twice as quickly despite Iwao using "the same tools and techniques." Around 82,000 terabytes of data were processed overall. While GMP is a general-purpose library for arithmetic on large numbers, it also works very well for such special tasks as computing a silly number of digits. In 2019, the calculation (which figured out a third as many digits as the most recent attempt) took 121 days. These formulas can be used as a digit-extraction algorithm for pi digits. Do we really need 31 trillion Well, no, probably not. But why do we care If you give me the first 39 digits of pi, I can tell you the width of the known universe within one hydrogen atom (See Numberphile’s video for how). Her job involves showing off what Google Cloud is capable of, so it's not too surprising that Iwao tapped into the power of the platform to perform the calculation. More interesting examples are given by (31) and (32) where is a Bernoulli number (Plouffe 2022). There are many ways to calculate the digits of pi you can use random sampling, geometry, calculus, etc. In a blog post, Iwao wrote that finding as many digits of Pi as possible is a way to measure the progress of compute power. Just specify how many digits you need and youll automatically get that many pi digits. Twitter: TPointMathMusic:'Carefree' Kevin MacLeod (incomp. Iwao and her team are working with Guinness World Records for official validation of their achievement as a world record. Forget the complicated formulas Here is a super-easy and fast way to calculate many digits of Pi. The benchmark has been broken a few times since then, including when researchers from a Swiss university calculated Pi to 82.8 trillion digits last year - twice as many as the Google team attained a few years back. Iwao and her team previously set the record in 2019 when they carried out a calculation to an accuracy of 31.4 trillion digits. Iwao says that the team has calculated the mathematical constant to 100 trillion digital decimal places. For this to work, make sure your calculator is set to Degrees. 2 Plug your number, which we'll call x, into this formula to calculate pi: x sin (180 / x). As you can see, there is quite a difference between the calculated and actual number of sides, but the scale of our estimation was correct. ![]() The bigger the number, the more accurate your calculation will be. With the help of a python script and some patience, I was able to calculate the exact number of sides we need. Google Cloud developer advocate Emma Haruka Iwao and her colleagues once again claim to have calculated Pi to a new record number of digits. Calculating Pi Using a Limit 1 Pick a large number. ![]()
