Zu Chongzhi (born 429, Jiankang [modern Nanjing, Jiangsu province], China—died 500, China) was a Chinese astronomer, mathematician, and engineer who created the Daming calendar and found several close approximations for π.
Zu Chongzhi was a Chinese mathematician and astronomer. He introduced the approximation 355113\large\frac{355}{113}113355 to π\piπ which is correct to 6 decimal places. Skip to content
Zu Chongzhi is known for his accurate approximation for π for the following 900 years. His best approximation was between 3.1415926 and 3.1415927 (355/113). Zu also calculated one year as (≒365.24281481) days, which is close to today's 365.24219878 days.

7 which is an. 7. approximation for p already given by ARCHIMEDES. A source from the 7th century reported that if you looked at a circle with a diameter of 10 000 000 chang, you knew that by the calculations of ZU CHONGZHI the circumference of this circle was more than 31 415 926 chang and less than 31 415 927 chang (1 chang ≈ 3.58 metres).
