What? Java has made use of extended precision floating point on x86 (well, x87) since 1.2. There is actually a proposal to stop doing this now that the x87 instructions are no longer the best way to do floating-point arithmetic [1].
Or is this about something else?
EDIT: Why am i asking here? I asked on the Reddit thread.

- cpleppert 5y agoGlad I wasn't the only one to notice that. No one idea what he could possibly mean but given that Java hasn't used x87 in forever and there is no reason to ever want to use them I guess he is just completely wrong here?
- twic 5y agoBased on the response on Reddit, yes, i think they are just confused.
