Another Ramanujan Trick

               4*arctan(1) = 3,1415926535897932384626433832795+

which uses just 2 digits and one function, which is many orders of magnitude simpler than your function which gives the root of the 34th-degree polynomial, and further agrees with infinitely many correct digits of Pi.

Surely going the whole hog would be arccos(-1)?
