Description Michael Rys 2005-05-13 21:17:18 UTC 
Since 0 and -0 compare equal anyway and many rounding functions (checked C# 
and SQL) do not special case the range -0.5e0 and -0e0, we should not special 
case rounding and allow results to be 0 instead of -0.
Comment 1 Michael Kay 2005-05-13 21:22:29 UTC 
I think it's appropriate during a last call for comments on XPath 2.0 to
question things that are new in XPath 2.0, but if we want to make changes to
behaviour that was defined in XPath 1.0 it seems a little bit odd to be
proposing the change now.
Comment 2 Ashok Malhotra 2005-05-20 22:14:24 UTC 
The joint QT WGs agreed to adopt this suggestion at the joint meeting on 5/19/2005.

Comment 3 Michael Kay 2005-05-21 07:41:52 UTC 
Just to be clear, the decision was that it should be implementation-defined in
this case whether +0 or -0 was returned. - Michael Kay
