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
it normal just for programmers to write (small) articles like
this? I write them, and other programmers I know write similar
things. Maybe to program you need (among other things) active
linguistic centers in the brain :-)
