Well, just wait a second. Seems to me that years ago (I probably still
have the article), I recall an HP Journal publication that proposed to
represent decimal numbers with a decimal point with a binary integer part
and a fractional part made up of groupings of 10 bits to represent 000-999.
I don't recall the gist of the perceived advantages. But one might argue
that this was a case of a hex number with a decimal point.
