JavaScript Number prototype Property
Example
Create a method that gives the number object a property that returns the number's half value:
Number.prototype.myMet=function()
{
this.myProp=this.valueOf()/2;
}
{
this.myProp=this.valueOf()/2;
}
Make a Number object, then call the myMet method:
var n = new Number(55);
n.myMet();
var x = n.myProp;
n.myMet();
var x = n.myProp;
The result of x will be:

Definition and Usage
The prototype constructor allows you to add new properties and methods to the Number() object.
When constructing a property, ALL number objects will be given the property, and its value, as default.
When constructing a method, ALL number objects will have this method available.
Note: Number.prototype does not refer to a single number object, but to the Number() object itself.
Note: Prototype is a global object constructor which is available for all JavaScript objects.
Browser Support
The prototype property is supported in all major browsers.
Syntax
