Technically, because dix gives us back ints, I just fill integral in,
and leave frac as 0. At some point, if we have this sort of
resolution, it would be useful, so I left it this way for now.

Simply because I didn't know if it was allowed because of politics. I
asked a little while in the IRC channel and somebody suggested to just
move it into Xmd.h.
