There might be a better, more local, way of doing it, so take the following as an
existence proof: if you customize the variable org-calc-default-modes and change
the calc-float-format to (fix 2), the table will recalculate to your expectations.

I don't know how to stitch together the better solution however, so I leave that
as an exercise for you :-)
