In comment #2, Michael Kay wrote, "4. (sqrt) fixed. I have also changed the
specification so that the square root of negative zero is positive zero as this
seems more consistent, but I'm open to persuasion on this."

I don't have a copy of IEEE-754 handy, but I'm almost certain that sqrt of
negative zero is negative zero according to that standard.  If I'm correct, I
don't think it would be a good idea to deviate in this regard without a very
strong rationale.
