24 ECMA Section: 15.7.1 The Number Constructor Called as a Function
28 Description: When Number is called as a function rather than as a
29 constructor, it performs a type conversion.
30 15.7.1.1 Return a number value (not a Number object)
31 computed by ToNumber( value )
32 15.7.1.2 Number() returns 0.
34 need to add more test cases. see the testcases for
35 TypeConversion ToNumber.
