2ππ
Pi is expressed by the Greek letter π (pronounced pài), which is a constant (approximately equal to 3.1415926535 8979323846), representing the ratio of circumference to diameter. It is an irrational number, that is, an infinite cycle decimal.
Around 480 A.D., Zu Chongzhi, a mathematician in the Northern and Southern Dynasties, further got the result accurate to 7 decimal places, and gave the insufficient approximation 3. 14 15926 and the excess approximation 3. 14 15927. In the following 800 years, the π value calculated by Zu Chongzhi was the most accurate.
On March 4th, 20 19, Google announced that Emma, a former Japanese Google engineer, with the help of Google's cloud platform, calculated the pi as 3 1.4 trillion digits after the decimal point, namely 3 14 15926535897 digits, and 201.
