Comment (by jdemeyer):
I consider this a bug:
> It is possible to construct a ball whose parent is the real ball field
with precision p but whose midpoint does not fit on p bits. However, the
results of operations involving such a ball will (usually) be rounded to
its parent’s precision.
It causes too much confusion for example with the `round()` function. It's
also too different from all other places in Sage which handle precision.
