Comment(by mhampton):
I don't understand why we can't just renormalize the cddlib output.
This sort of thing is still a problem with PPL: with this same input, the
PPL output for the H-representation is integer-valued, and the integers
are big (presumably converted from double precision - ?). I think this
would have to rescaled somehow when using numerical 'fields'. (Btw, the
output of PPL is different on linux versus OS X, which is mildly
disturbing).
