The problem is that 0 can take signs. Since it can then we have to be explicit about it. If you say 'positive' then +0 is valid, similar issue with 'non-negative'. However, -0 would of course not be valid for 'positive' or 'non-negative'. We just need to be clearer when it comes to writing text about values.

We should get in the habit of saying 'non-zero' if we want to exclude 0.
