Avoid negative shift.

When filling in fractional digits in a fixed representation we
might use all existing digits. When this happens, we can not look
at the next digit to see if we should round up.

Before this fix, we tried to shift by a negative amount to see if the
(non-existing) next bit was set to 1 (requiring the number to be rounded up).

Fixes #41.
