>nan > nan is false, while nan < nan is true.

If this wrong behavior from jq, or some artifact consistent with how the floating point spec is defined, surprising, but faithful to IEEE 754 nonetheless?

IIRC, any comparison using a nan must fail (return false) according to the IEEE spec.

I think it is a bit more complex, since NaN is defined to be "unordered" with respect to all other values (including other NaNs), and so any relation for which unordered values result in true (e.g., compareQuietNotEqual) will return true. (See section 5.11)

I used Bard after trying unsuccessfully to decipher the wikipedia page and Bard says, according to IEEE 754, nan < nan should return false (0); while nan > nan should return false (0)

I wish there was some version of Wikipedia for people who speak good English (not Simple English), but aren't assumed to already be experts on the topic. Technical articles are pretty much impenetrable.

So you basically wish for Wikipedia to also feature simplified explanations of technical topics.

I don't think "good English vs simple english" plays into this.

It's not like the problem for technical articles being impenetratable on Wiki is that Wiki doesn't have an intermediate level between expert-talk and simple english.

It's just that it doesn't have simple english explanations of some technical topics.
