NAME
    XML::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 XML::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.
