IS Pi a finite or infinite number?

What do you guys think???

Also when do you think mankind will discover the answer to this most important question?

After 32 didgets (something like that) it becomes mathematically insegnificant.  But 3.14... is only an approximate, the exact value is something like (14-square root of 2)/4.  Usually you will use the exact value rather than messy approx. decimals.
