Are you referring to this discussion?

I understand the original reason for retaining it before, but this discussion is outdated for this PR.

`Unsafe` does not provide `getFloatUnaligned`/`getDoubleUnaligned` and `putFloatUnaligned`/`putDoubleUnaligned`, so we must convert floating point numbers to integers here. This problem is no longer hidden behind `VarHanle`, so we have to face it.

In addition, these comments are indeed wrong and may mislead users. I saw this mentioned in the previous discussion, but I don't know why the document was not cleaned up. I think it's time to clean it up.
