Apparently it wasn't, as the commenter who originally used the term has now clarified that they did indeed mean non-deterministic. You misunderstood them.
So maybe being specific about terminology here isn't just pointless pedantry?
He can't attest to them being the same ones in the paper I linked, but I can. Everything he's said is in line with the situation detailed within.
He and I seem to understand each other. I get what he's saying. How the issues with IEEE754 give rise to the nondeterminism he's talking about. I should, I wrote a whole system of libraries to deal with them. Do you understand the conversation? Because it seems like you think we're talking about two unrelated things and you're still arguing over terminology.
