Do we need to use `@implNote` here? Since choices are `double`s (as in the class description), I think we can safely say this returns a `Double` as in normative text. If some implementation returns an `Integer`, I think it is a bug. Returning a `Double.NaN` for no-match may be considered implNote though (one might throw an exception). ------------- PR Review Comment: https://git.openjdk.org/jdk/pull/24361#discussion_r2023404649 PR Review Comment: https://git.openjdk.org/jdk/pull/24361#discussion_r2023462230
