The name could be simplified indeed. Maybe formatByteSizeTo()?

Some comments about the API:

1) don't use a bool longPrefix, use an enum {LongFormat, ShortFormat}
 (why call it "prefix" when it's about the suffix, in English at least? ;)
 Maybe LongFormat is too generic (especially in KLocale which has date formats etc.),
  something like LongSizeFormat and ShortSizeFormat would be better,
  even if it's a bit longer to type.

2) the int precision needs documentation, but also maybe a default value?
I see that the existing code calls it always with 1, so maybe the default value
should be 1. If a good default can be found for the enum too, then the calling
code can be simplified in most cases to
  locale->formatByteSizeTo(size, KLocale::GigaByte)
