But if `x` is `-0.0`, you're back to the same problem that `-0.0 >= +0.0` actually turns out to be `true` and not `false`, hence the return value will be `-0.0`.

Looking at the actual implementation[0], `doubleToRawLongBits` is again here to take care of this edge case.

Roundtrip tests are great when you don't have a gold standard. It allows for at least consistency across operations. I've done a bunch and found quite a few corner cases. I also did a few roundtrip tests in RGB spaces where being exhaustive was no longer feasible. For those I ended up iterating over the whole RGB space but skipping values in each component by different prime values, to try and cover as much of the space as possible:
