Rounding mode to round towards {@literal "nearest neighbor"}
unless both neighbors are equidistant, in which case round up.
Behaves as for {@code RoundingMode.UP} if the discarded
fraction is ≥ 0.5; otherwise, behaves as for
{@code RoundingMode.DOWN}. Note that this is the rounding
mode commonly taught at school.
