I thoroughly enjoy the read, highly recommended.
Kahan excerpt from above:
"I don't feel that the architects of Java are wicked so much as premature
to think that they can write a universal language for every man to write
everything to run everywhere. That isn't going to happen, it's going to be
a turf war -- Bill Joy against Bill Gates. It's a lousy reason to write a
language, to write it in order to precipitate a turf war to bring things into
a territory more advantageous to Sun than the current situation."
I am reading another Kakan article on Java and IEEE (not yet finished).
It seems there is good reason even for sign of zero. (+/- 0.0)
IEEE people certainly know what they are doing ...

p.s.
my naming of thread maybe misleading.
I was only proposing a *default* precision setting.
