Review Comment:
Just clarifying: this is saying that as long as the literal isn't -0.0, we
don't have to normalize it? And it doesn't look like there's any way to define
a literal NaN, so we don't handle that case?

Review Comment:
Since you added these steps to the testing commands, does it makes sense to
duplicate them below for the generation commands?
