man XML::XPath::Number () - Simple numeric values.
NAME
XML::XPath::Number - Simple numeric values.
DESCRIPTION
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.
API
new($num)
Creates a new XML::XPath::Number object, with the value in CW$num. Does some rudimentary numeric checking on CW$num to ensure it actually is a number.
value()
Also as overloaded stringification. Returns the numeric value held.
