JavaScript | Math.SQRT2 property

The Math.SQRT2 is a property in JavaScript which is simply used to find the value of square root of 2, whose value is approximately 1.4142.
That is, √ 2  = 1.4142
Difference between property and function in javascript.
Property in JavaScript is nothing but a value whereas method is a function this can be understood anith the help of a example given below.

<script> 
  
// car is an object. 
var car = {}; 
  
// car.name is a property of the given object. 
car.name = "Audi"
  
    // car.sayModel is a function of the given object. 
    car.sayModel = function() { 
        document.write("A8 <br>"); 
    
                  
    // printing property value. 
    document.write(car.name + '<br>'); 
                  
car.sayModel();     
</script>

Output:

Audi
A8

Here as we can see that property of the object car, is going to store the string as “Audi” and it can be accessed with car.name.
sayModel is a method i.e, a function of the object and it can be accessed with car.sayModel().
It can be noticed that sayModel is just a function which use ().



Syntax:

Math.SQRT2;

    Parameters: Here nothing is passed as a parameter because, Math.SQRT2 is not a function but it is a property.

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

Example:

Input : Math.SQRT2
Output: 1.4142135623730951

Explanation:
Here simply value of the square root of 2 is shown as output.

Let’s see JavaScript code for Math.SQRT1_2 property:

    <script>
      // Here value of Math.SQRT2 is printed.
      document.write(Math.SQRT2);
    </script>

    chevron_right

    
    

    Output:

    1.4142135623730951
  • Example 2: Value of square root of 2 can be printed as in the form of function as shown below.

    <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
      document.write(get_Value_of_square_root());
    </script>

    Output:

    1.4142135623730951
  • Errors and Exceptions: Here we consider Math.SQRT2 as a function but in actual it is a property that is why error as output is being shown.

        //but in actual it is a property that is why error
        // as output is being shown.
        document.write(Math.SQRT2(12));
      </script>

      chevron_right

      
      

      Output:

      Error: Math.SQRT2 is not a function

    Application: It’s 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.
    Let’s see JavaScript program on this application:

        document.write(Math.SQRT2);
      </script>

      chevron_right

      
      

      Output:

      1.4142135623730951
