A volte una visione dall'esterno è molto più "chiarificante"...

By now you've probably seen a lot of the brouhaha over a bug in the newest version of Excel, 2007. Basically, multiplying 77.1*850, which should give you 65,535, was actually displaying 100,000.

Before I try to explain this, I should disclose that I did work on the Excel team, but that was thirteen years ago. I haven't been there for a long time. I don't even think I know anyone on that team any more. I'm just trying to explain the bug a little bit as a public service.
