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 :)
- IEEE754 3y agoCorrect.
- petters 3y agoUsername checks out. There is an other article about fp32 vs fp16 the front page for you as well!
- tromp 3y agoFixed:-)
- SAI_Peregrinus 3y agoI 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.
- stephencanon 3y agoIEEE 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).
- SAI_Peregrinus 3y agoThanks, clearly it's been too long since I read the spec.
