We're going a bit away from the original topic now but of course, that
doesn't change unless everyone does the same. I wouldn't say it's "the
solution" because I feel it's more like taking a shortcut and avoiding
the real problem. While someone isn't making a final decision on a
standard, we will however know immediately what is meant when someone
says KiB (while the ambiguity is still indifferent with kB).

At least while I was in school, I learned that kilo == 1000. When I
started using computers, nobody told me when kilo == 1000 and when kilo
== 1024. I also wondered why I had "less" total storage capacity than
advertised.

Even while I studied electronics in collage, I had to teach my own
teacher that HDD manufacturers measures kilo as 1000 and not 1024 (and
that's why the number on the label is different from what you see in
Windows). So it's not easy. :(

I just noticed that I said this, but I meant that's what HDD
manufacturer do.

In the case of HDD manufacturers measuring memory in a decimal form is pure
economics that has nothing to do with electronics -- it is much more easy to
sell a 1.5 TB hard drive versus 1.36 TB one. And for the general public it
doesn't make any sense to argue about the difference between GB or GiB
either (I'm sure 90% of the population never even heard of the GiB
notation). It matters only when the most inquisitive ones look up a drive's
specs in My Computer and call up a customer service... but that is a
diffeent issue.

Guys, I'm going to drop the original problem, i.e. the difference between
reported 3.96GB and the actual 4.00 GB. I will simply round it up if the
difference is less than 0.05. That seems what MS is doing in the latest OS's
anyway.

Thanks everyone who contributed, and especially Jackie.
