Note, that along with further improvements to `equals`, commit a9cbbe5, boldly suggests dropping `&` in `hashCode` to fold its implementation into a single call to a utility method. Now, I'm not an expert, but the `test/jdk/java/math` tests pass. To my (non-expert) opinion, `&` was also dulling down `hashCode`; but I'm eager to hear comments from those who understand that more than I do. Perhaps this PR needs to be accompanied by benchmarks. ------------- PR Comment: https://git.openjdk.org/jdk/pull/14630#issuecomment-1605381393
