I don't see the problem: the -4 row represents -4.x and -5.x, the
latter first since they are smaller. The display is generally
ambiguous since you get exactly the same value if you replace b[2]
with -5, but that seems to be a generic problem, just like the fact
that you cannot see whether the lone zeroes represent 4 and 7 or 5 and
8.
