That is correct. But we were talking about how the == operator compares zeros. According to IEEE 754, -0 == +0 even though their bit patterns are not identical.

- andreareina 4y agoYou mean nan right?
- sampo 4y agoYes. I mean nan != nan. I don’t know why I wrote inf. Thank you for correcting.
- MauranKilom 4y ago> But we were talking about how the == operator compares zeros Well, you were and I wasn't, and it wasn't clear whether you meant to contradict my point. I guess I could've made it more clear that I meant "using == to denote bitwise equality here only" and not "btw, == is bitwise for floats", but either way it should be clear now.
