    scale: doc: set_digits doesn’t round retroactively
    
    Whether it should is an open question, but for now, the documentation
    should clearly indicate that currently rounding is only applied upon
    changes to the value, not to the existing value when ::digits changes.
    This is already clear in the doc for the underlying Range::round-digits.
