So the floating point number classification now goes like:
1. Finite 1.1. Normalized finite 1.2. Denormalized finite 2. Infinity 2.1. Positive infinity 2.2. Negative infinity 3. Not-a-number 3.1. Quite not-a-number 3.2. Signalling not-a-number
I believe the term normal is more common nowadays than normalized or non-denormalized. I believe the term subnormal is more common nowadays than denormalized. So it would make sense to have the functions is_finite() is_normal() is_subnormal() is_infinity() is_plus_infinity() is_minus_infinity() is_nan() and possibly is_quite_nan() is_signalling_nan() The last two are tricky to implement though. --Johan Råde
