==Significance of Liu Hui's algorithm==

Liu Hui's {{pi}} algorithm was one of his most important contributions to ancient Chinese mathematics. It was based on calculation of {{math|N}}-gon area, in contrast to the Archimedean algorithm based on polygon circumference. With this method Zu Chongzhi obtained the eight-digit result: 3.1415926 < {{pi}} < 3.1415927, which held the world record for the most accurate value of {{pi}} for 1200 years, even by 1600 in Europe, the Dutch mathematician [[Adriaan Anthonisz]] and his son obtained {{pi}} value of 3.1415929, accurate only to 7 digits.<ref>Robert Temple, The Genius of China, a refined value of pi, p144-145, {{isbn|1-85375-292-4}}</ref>
