You can absolutely have two ranges which require 7.5 bits to store each (0-180) and write them to 15 bits of storage.

Just because physical hardware is more or less restricted to integer bit quantities doesn't mean fractional bits aren't a useful concept.

Sure, I accept I was wrong, and millibits may have some niche usage. That said, the comment I was responding to was describing hardware with "4 mb" of ram. There's no confusion in that case.
