XML::XPath::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.


Creates a new XML::XPath::Number object, with the value in $num. Does some rudimentary numeric checking on $num to ensure it actually is a number.

Also as overloaded stringification. Returns the numeric value held.
