    The Number is a javascript object that represents numerical date, either integers or floating-point numbers.

    The syntax for creating a number object is as follows:

    var num = new Number(number);

    If it receives a non-number argument, then the argument cannot be converted into a number, it returns NaN (Not-a-Number).

    Javascript provides few Number Properties . Here is a list of each property and their description:-

    MAX_VALUE-  It belongs to the static property . The largest possible value a number in JavaScript can have 1.7976931348623157E+308 .

    The syntax is:

    var val = Number.MAX_VALUE;

    MIN_VALUE - The smallest possible value a number in JavaScript can have 5E-324 .

    The syntax is:

     

    var val = Number.MIN_VALUE;

      NaN- Equal to a value that is not a number.

    The syntax is:

    var val = Number.NaN;

    NEGATIVE_INFINITY - A value that is less than MIN_VALUE. Because NEGATIVE_INFINITY is a constant, it is a read-only property of Number.

    The syntax is:

    var val = Number. NEGATIVE_INFINITY;

    POSITIVE _INFINITY- A value that is greater than MAX_VALUE .

    The syntax is:

    var val = Number. POSITIVE_INFINITY;

     

    Prototype - A static property of the Number object. This prototype property is used to assign new properties and methods to the Number object in the current document . Prototype is a global property associated with all the objects.

    Syntax ix:

    object.prototype.name = value;

    Constructor - Returns the function that created this object's instance. By default this is the Number object.

    Syntax is:

    number.constructor()
