Can you please file a follow up issue to write a test (gtest?) for the `f2hf` and `hf2f` methods? If a bug is lurking in those it will otherwise be really hard to track down. (Perhaps an alternative to a gtest is to to somehow call those methods natively from Java using Panama, then we can reuse all the existing testing logic.)
