This notion of equivalence could have a method to provide the predicate directly, rather than relying on one of several expressions listed in the documentation ([JDK-8295391](https://bugs.openjdk.org/browse/JDK-8295391)).

I'll acknowledge possible bike-shedding on the name of the method. I choose "equivalent" to make the discussion in Double.
