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.
