ECMA Section: 15.7.2 The Number Constructor
|
|
15.7.2.1
|
|
15.7.2.2
|
|
|
|
Description: 15.7.2 When Number is called as part of a new
|
|
expression, it is a constructor: it initializes
|
|
the newly created object.
|
|
|
|
15.7.2.1 The [[Prototype]] property of the newly
|
|
constructed object is set to othe original Number
|
|
prototype object, the one that is the initial value
|
|
of Number.prototype(0). The [[Class]] property is
|
|
set to "Number". The [[Value]] property of the
|
|
newly constructed object is set to ToNumber(value)
|
|
|
|
15.7.2.2 new Number(). same as in 15.7.2.1, except
|
|
the [[Value]] property is set to +0.
|
|
|
|
need to add more test cases. see the testcases for
|
|
TypeConversion ToNumber.
