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