Four months to arrive at 31,415,926,535,897 digits

Emma Haruka Iwao, a developer advocate at Google Cloud, has celebrated Pi Day (3/14) by setting a new Guinness World Record for calculations of the beautiful mathematical constant, reaching a number with more than 31.4 trillion (ha!)

Researchers have been competing to calculate the most digits of Pi for years – often with the help of supercomputers – but this announcement marks the first time the record has been broken using a commercial cloud service, exceeding the previous best by about nine trillion digits.

For her experiment, Iwao relied on y-cruncher, a free app originally developed by Alexander Yee to turn Pi calculations into a benchmarking and stress-test tool for overclocking enthusiasts – which has been used in previous world records.

"This method of computation and verification has remained the same for the previous six times the Pi record has been broken.

All advances have been entirely in software and hardware," Yee explained.
