TFA neglected to mention that floats have an "infinity" value, quite a bit larger than any 64 bit busy-beaver.
(And before anyone says it's not a number, call `isnan` with an infinity and get back to me :)

Correct.
Username checks out. There is an other article about fp32 vs fp16 the front page for you as well!
I don't believe IEEE 754 specifies which infinities it encodes as its positive and negative infinity. I'd tend to treat it as the surreal equivalence class {0,1,2…|}, but it might be any of the others.
IEEE 754 is very clear that the infinities are the endpoints of the extended real line (and hence also the extended integers, which matches your assumption).
Thanks, clearly it's been too long since I read the spec.
Fixed:-)
