This rule is very simple... and easy to remember... and *wrong*.
What would be the result of
(2 / 3) * 3
according to this rule? Well, 2.0 of course. But in reality it's 0,
as we all know.
For the record, I'm all for 2/3 giving 2/3 (a floating point
approximation thereof, or better yet, a rational)
Bye, J
