The Math.SQRT2 is a property in JavaScript which is simply used to find the value of the square root of 2, whose value is approximately 1.4142. That is,

√ 2  = 1.4142

Syntax:

Math.SQRT2;

Return Values: It simply returns the value of the square root of 2, whose value is approximately 1.4142. 

Below is an example of the Math SQRT2 Property.

Example: 

javascript




<script>
    // Here value of Math.SQRT2 is printed.
    console.log(Math.SQRT2);
</script>


Output:

1.4142135623730951

Example: Here the simple value of the square root of 2 is shown as output.

Input : Math.SQRT2
Output : 1.4142135623730951

More codes for the above property are as follows: 

Program 1: The value of the square root of 2 can be printed in the form of a function as shown below. 

javascript




<script>
    // function is being called.
    function get_Value_of_square_root()
    {
        return Math.SQRT2;
    }
     
    // function is calling for getting
    // value of square root of 2
    console.log(get_Value_of_square_root());
</script>


Output:

1.4142135623730951

Program 2: Here we consider Math.SQRT2 is a function but in actuality, it is a property which is why the error as output is being shown. 

javascript




<script>
    // Here we consider Math.SQRT2 as a function
    // but in actual it is a property that is why error
    // as output is being shown.
    console.log(Math.SQRT2(12));
</script>


Output:

Error: Math.SQRT2 is not a function

Program 3: Its application is to find the value of the square root of 2 which is done with the help of this property. In mathematics, it needed a lot. 

Example: 

javascript




<script>
    // Value of Math.SQRT2 is printed.
    console.log(Math.SQRT2);
</script>


Output:

1.4142135623730951
