Had a slight obsession with this ratio since secondary school when I realised someone (think was this interesting maths teacher) pasted a looooong printout of pi along the wall of the library. I recall pi to be 3.1415926. Period :p
Read the other day that some guy broke the world record for reciting pi to some tens of thousands of decimal points.. But wait, it only gets better; NacenteNet linked to this website that gives the number to a freaking million decimal points! Everyone must see!
Btw, 22/7 is not the exact pi ok, hence the ~ I go to MathWorld to feed my obsession on numbers, esp recreational maths - mf likes :)
