My formula takes 35 iterations to reach 10 places of pi.
Gauss (Salamin and Brent) takes 3 iterations to reach 10 places of pi.
Ramanujan methods (two of them) takes just 1 iteration to reach 10 places of pi.
You can see for yourself. Ramanujan expression converges rapidly.
I was unable to test Chudonovsky expression.
My algorithm is the simplest. 35 iterations in a jiffy.
