Probably not.  But the default rounding mode was good enough for the
proof of concept.

That was the point of my "A more accurate treatment" comment.

But I wasn't sure how small epsilon should be, so I didn't suggest.

Perhaps 0x1p-16?

I know C better than C++.  Does C++ already have a routine for this?
