public final class RoundingModeNames
extends Object

The words ROUND's optional third argument takes. Two, and only two: HALF_AWAY_FROM_ZERO — the default, which rounds a tie away from zero — and HALF_TO_EVEN, banker's rounding. The comparison is case-insensitive, live-verified in both cases, and nothing is trimmed: a word with a space on either side names no mode.

Kept beside Round, which reads the same argument to pick a RoundingMode, and shared with the compile-time check that refuses anything else: the two must agree about what a mode IS, or a word one accepts would be refused by the other.
