JavaScript - The Number Object

JavaScript - The Number Object

The Number object represents numerical date, either integers or floating-point numbers. In general, you do not need to worry about Number objects because the browser automatically converts number literals to instances of the number class.


The syntax for creating a number object is as follows −
var val = new Number(number);
In the place of number, if you provide any non-number argument, then the argument cannot be converted into a number, it returns NaN (Not-a-Number).

Number Properties

Here is a list of each property and their description.

The largest possible value a number in JavaScript can have 1.7976931348623157E+308

A value that is less than MIN_VALUE.
