Please note that the binary prefixes kibi and mebi not might be used
for other things than bytes as well. And if we were trying to be
precise, wie might want to use "octets" instead of bytes anyway ;-)

I think it's largely a matter of taste and experience whether you
prefer (2 << 30) or (2 * 1024 * 1024 * 1024). It depends a lot on how
much you work with such numbers - I prefer (2 << 30) because it's
shorter, others find the "* 1024" notation easier to read.

But no matter what you prefer -@least both variants are readable.

Why should we use any such macros at all? Just write the plain
numbers in the code so everybody can understand it without having to
look up the definition.

Best regards,
