The disc drive companies use base 10, so 2 Gigabytes
would be 2E09 bytes.

RAM manufacturers use base 2, so 2 Gigabytes would be
2.147etcE09 bytes.

We had that problem with a program that was guaranteed to
install in "10 Megabytes" of disc space, but actually occupied
more than 11 -- there was a lot of hair-pulling over that incident.
