Ask HN: How is it possible to get -0.0 in a sum?

5 gus_massa 0 8/2/2025, 1:58:43 PM
I'm looking for corner cases where he result is -0.0. As far as I know, the only way to get -0.0 in a sum is

  (-0.0) + (-0.0)
Does someone know any other case in IEEE 754?

Bonus question: What happens in subtractions? I only know

  (-0.0) - (+0.0)
Is there any other case?
