Can anyone tell me the algorithm of pi

representations are thought in the form utilized by Horner's method. E.g., in the decimal system we have

(1)√2= 1.41421 ... = 1 + 1/10 (4 + 1/10 (1 + 1/10 (4 + 1/10 (2 + 1/10 (1 + 1/10 ( ... ,π= 3.14159 ... = 3 + 1/10 (1 + 1/10 (4 + 1/10 (1 + 1/10 (5 + 1/10 (9 + 1/10 ( ... ,

But was there a positional system in which π was known? As S. Rabinowitz has realized, there indeed was such a system albeit an unusual one. The starting point was the series



which also can be written as



or, in the Horner form,

the answer will be

9 x 8 divided by (5-3)=36
