> An arb ball has no intrinsic precision, and (more or less because of
that), an element of `RealBallField(p)` can have a midpoint that doesn't
fit on `p` bits. The `round()` method rounds such elements to the
precision of their parent.
When asking these questions above, I'm not just asking for myself
personally. It means that the code on the branch should be clarified.
