FYI, the IEEE floating point standard requires support for positive and negative zero. See Signed_Zero and IEEE_754 for more. So more like a "most computers and programming languages" thing than a Perl thing. Elda Taluta; Sarks Sark; Ark Arks	[reply]

I'll accept either way, under the condition it's consistent with what you'd return on `dualvar(-0.0, ...)`	[reply] [d/l]
