=head1 NAME

XML::LibXML::Number - Simple numeric values.

=head1 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.

=head1 API

=head2 new($num)

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

=head2 value()

Also as overloaded stringification. Returns the numeric value held.
