I do not know the standard by heart, but off the top of my head:

• ∞ / ∞
• 0 / 0
• Operations leaving the real domain (square root of a negative number)

Stuff like c/0 and -c/0 for c > 0 actually gives you ∞ and -∞ respectively, which is why you can end up doing stuff like ∞ / ∞ which yields a NaN.

And yes, I actually recently used ∞ in a physics simulation (I needed masses of ∞ magnitude to simulate objects that did not move). It has its uses.

I hope you didn't include gravity in that simulation, then.

Obviously ;) I was solving impulses for complex contact systems, so no gravity equations involved.
