You have omitted the detail that double.nan !is double.init.
On a more general note, I know many professionals in other fields
that never write small articles about what they are doing. So is

Your example:
float f;
if (condition1)
f = 7;
... code ...
if (condition2)
++f;

Why would it matter what is "normal"?
It matters to me because I am curious.
Why aren't my friends that work or study chemistry writing free
small online articles like my programmer&CS friends do? Maybe
it's systematic differences in their brain brain? Or it's just
