The docs recommend that you use dedicated methods instead of calling classify directly, although there isn't actually a way of checking if a number is subnormal without calling classify. There are dedicated methods for all other forms, excluding is_zero (which is just == 0.0 anyway).

Looks good!

Can you open a tracking issue for the is_subnormal feature, and add its number in the unstable attributes in this PR?

Somehow didn't notice that this had feedback! Was about to bug the thread again and see what was holding this up.

Will make those changes right now. :)

Rebased, filed tracking issue, and made the suggested change. Was waiting on a confirmation that this would be good to implement before I filed a tracking issue, since I didn't want to file something for a not-yet-approved change.

Let me know if you need anything else before merging. :)

Yeah that's good. :)

Rebased, filed tracking issue, and made the suggested change.

I don't see the changes in this PR though. Did you push the right commit?
