refer to the encoding as a whole, however. It was a useful abbreviation/jargon for committee use, but it does not do justice to the very neat encoding of the exponent, etc., devised by Dan Zuras and others. It's not even the case that the whole coefficient
is encoded using DPD.</span><o:p></o:p></p>
