Re: Question on Pi

Hi all,

I'm looking for an algorithm that allows to calculate
a specific digit of Pi directly, whereas the only
parameter is the position of the digit.

e.g. f(2) = 4, f(3) = 1, ... and so on.

Does such an algorithm exist at all?
If yes, do you have a Java implementation by chance?

Thanks in advance,

Andre


  Hi,

  You may have a look at Fabrice Bellard's Pi page :
   http://fabrice.bellard.free.fr/pi/
  or directly http://fabrice.bellard.free.fr/pi/pi_n2/pi_n2.html
  you should even find C code with a running time of O(n^2)

  You may look too Simon Plouffe's work here :

  Hoping it helped,
