Using Proposition~\ref {prop:relerror} we obtain a relative error of $\relerror (\appro {\pi}) \leq 2^{-p}$ at precision~$p$, which would be enough for the following analysis. However, we can be a bit more -precise, knowing the first few binary digits of $\pi$: As soon as $p \geq 8$, +precise, knowing the first few binary digits of $\pi$: As soon as $p \geq 7$, +% for p=6, we get 25/8 < 201/2^6, for p=7 we get 101/32 > 201/2^6 we have $201/2^6 \leq \appro {\pi}$, so \[ \relerror (\appro {\pi}) |
