NAME

       Tree::XPathEngine::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 Tree::XPathEngine::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.

   Other Methods
       Those are needed so the objects can be properly processed in various contexts
