Apples and oranges. For any two different real numbers, there's a number between them. Integers work differently.

This is a bold assertion, and one that is not obviously true, especially in cases like 0.999... and 1.0

Those aren’t different real numbers. That’s the whole point of the conversation.

Obviously saying it is not obviously true is false if 0.999... == 1.0

Can something be true and not obvious?

Obviously not.

Which is the point in using the word obvious, obviously. Namely, using it to feel superior or to not provide a better argument.

When I use the word, the point is to call out the fact that I think it's obvious, so if others don't, they can explain why. Not to forestall any discussion.

Anyone who uses the word differently is doing it wrong.
