Since I haven't seen anyone else say it yet, if you are going to use a 12
digit approximation, how about using 3.14159265359 which is an even better
approximation than the one you use :-).

I find "3" is accurate enough for many purposes, though.

Be careful if you are determining pi by measuring the ratio of the
circumference of a circle to its diameter: a one tonne weight in a 10 metre
diameter circle will affect the value of pi in about the 24th or 25th
decimal place (general relativity and curvature of space-time etc.). If
you wish to try this, it's worth knowing that the correct value of
pi should be around 3.14159265358979323846264338 in flat space, although
the last two or three digits will be different with the one tonne weight
in place. :-).
