But there is one project which is very close to this target:

http://en.wikipedia.org/wiki/TeX


The number of digits after the dot sign in its version number is equal to the number of bugs found during its lifetime.

So, the fun starts:

$ tex --version
TeX 3.1415926

Count it yourself :-)

Unfortunately, it is near to impossible to reach this target in the modern industrial software engineering. But all the sw. engineers shall not forget about this real example :-)
