I know you can easily calculate digits of $\pi$ using summation by using the Bellard formula.
$$ \pi ={\frac {1}{2^{6}}}\sum _{n=0}^{\infty }{\frac {(-1)^{n}}{2^{10n}}}\,\left(-{\frac {2^{5}}{4n+1}}\right.{}-{\frac {1}{4n+3}}+{\frac {2^{8}}{10n+1}}-{\frac {2^{6}}{10n+3}}\left.{}-{\frac {2^{2}}{10n+5}}-{\frac {2^{2}}{10n+7}}+{\frac {1}{10n+9}}\right) $$
However, you still need to use summation for this. What I am wondering is: how can I extract a specific digit of $\pi$ using the Bellard Formula?
