Everybody who expected 0.6666667, raise your hands.  Put your hands down.
Now, everybody who expected 0.6667 raise your hands.  How about those who
expected 0.66666666666666663 (the "real" result of 2.0/3.0 on my computer)?
Anybody?

In all of those cases, the result was truncated or rounded.  2/3=0 is just
more obvious and predictable about it.
