on a more mathematical level, should two nan or two inf or two -inf be considered the same? It is improbable that two inf are the same when you are running a diff. If we agree that they should be considered the same, then this all looks great!

I asked myself the same question while doing this PR and I found links like this stating that inf==inf and -inf==-inf .
On the contrary, it seems that they agree that Nan!=Nan , but that's outside the scope of this PR.
Let me know if you prefer not considering two inf the same, I can easily adapt tests and code.

I think following convention is preferred over mathematical precision, so this sounds good to me 👍
