Well we do get email here at the Jersey City Desk and tonight Johnny would like to take some time out and answer a question for a reader.
Dear Frustrated, Johnny thinks the formula you're looking for to calculate the N-th digit of Pi is: Pi = SUMk=0 to infinity 16-k [ 4/(8k+1) - 2/(8k+4) - 1/(8k+5) - 1/(8k+6) ].
Hope that helps.
Time for Jersey City, After Dark
