The previous record was set in 2016 at 22459, 1577, 18361, which means that the Google employee has added nearly 10 trillion bits.

According to Iwao, he uses Google's cloud computing engine and runs about 25 virtual machines for 121 days. Peter Trueb, the creator of the 2016 record, used only one computer, which had a large 6TB hard drive, but lasted only 105 days.

Data show that the circumference rate is an infinite non-circular decimal. Chinese mathematicians Liu Hui and Zu Chong took the lead in accurately calculating the factorization to the next seven decimal points, i.e. the most classic 3.1415926, which lasted for more than 1000 years.
