File Name: 15.7.4.3-1.js

|
ECMA Section: 15.7.4.3.1 Number.prototype.valueOf()
|
|
Description:
|
|
Returns this number value.
|
|
|
|
The valueOf function is not generic; it generates a runtime error if its
|
|
this value is not a Number object. Therefore it cannot be transferred to
|
|
other kinds of objects for use as a method.
