XML::LibXML::Number − Simple numeric values.
This class holds simple numeric values. It doesn’t support −0, +/− Infinity, or NaN, as the XPath spec says it should, but I’m not hurting anyone I don’t think.
new($num)
Creates a new XML::LibXML::Number object, with the value in
$num. Does some rudimentary numeric checking on $num to
ensure it actually is a number.
value()
Also as overloaded stringification. Returns the numeric
value held.
