NAME

       JE::Number - JavaScript number value

SYNOPSIS

         use JE;
         use JE::Number;

         $j = JE->new;

         $js_num = new JE::Number $j, 17;

         $perl_num = $js_num->value;

         $js_num->to_object; # returns a new JE::Object::Number

DESCRIPTION

       This class implements JavaScript number values for JE. The difference between this and
       JE::Object::Number is that that module implements number objects, while this module
       implements the primitive values.

       Right now, this module simply uses Perl numbers underneath for storing the JavaScript
       numbers. It seems that whether Perl numbers are in accord with the IEEE 754 standard that
       ECMAScript uses is system-dependent. If anyone requires IEEE 754 compliancy, a patch would
       be welcome. :-)

       The "new" method accepts a global (JE) object and a number as its two arguments. If the
       latter is an object with a "to_number" method whose return value isa JE::Number, that
       object's internal value will be used. Otherwise the arg itself is used. (The precise
       details of the behaviour of "new" when the second arg is a object are subject to change.)
       It is numified Perl-style, so 'nancy' becomes NaN and 'information' becomes Infinity.

       The "value" method produces a Perl scalar. The "0+" numeric operator is overloaded and
       produces the same.

       Stringification and boolification are overloaded and produce the same results as in
       JavaScript

       The "typeof" and "class" methods produce the strings 'number' and 'Number', respectively.
