Liu Hui was the first Chinese mathematician to provide a rigorous algorithm for calculation of π to any accuracy. Liu Hui’s own calculation with a 96-gon provided an accuracy of five digits: π ≈ 3.1416.
Liu Hui’s π algorithm was invented by Liu Hui (fl. 3rd century), a mathematician of Wei Kingdom.
