[PATCH] doc: use gibi binary prefix instead of gigi

[PATCH] doc: use gibi binary prefix instead of gigi

[Dieter Dobbelaere]

Hi,


I propose to use the official binary prefix "gibi", established by International Electrotechnical Commission (IEC) and several other standards and trade organizations.
Weirdly enough, the term gigibyte is used in three places, whereas gibibyte is the only correct term.

See also https://en.wikipedia.org/wiki/Binary_prefix

I was unsure if this deserves a changelog item.


Best regards
Dieter
