I've seen before that Pi supposedly takes a lot of processing power to approximate because of its infinite series [tex]4\sum_{r=1}^\infty \frac{-1^{r+1}}{2r-1}[/tex]
However would it not be far quicker to use the infinite series to approximate [tex]arcsin{\frac{1}{\sqrt{2}}}[/tex] and then multiple the answer by 4? It seems to calculate Pi far faster to the small amount of terms I have done so far.
Preemptive thanks for an answer
