michael@0: 
michael@0:    Description:        When Number is called as a function rather than as a
michael@0:    constructor, it performs a type conversion.
michael@0:    15.7.1.1    Return a number value (not a Number object)
michael@0:    computed by ToNumber( value )
michael@0:    15.7.1.2    Number() returns 0.
michael@0: 
michael@0:    need to add more test cases.  see the testcases for
michael@0:    TypeConversion ToNumber.
