JavaScript | Math.LN2 property

The Math.LN2 is a property in JavaScript which is simply used to find the value of a natural log of 2.Natural log is of base e which is represented as ln. So, the natural log of 2 is represented as ln(2) whose value is approximately 0.693.

Difference between property and function in JavaScript
Property in JavaScript is nothing but a value whereas method is a function this can be understood with the help of an 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.LN2;

Parameters: Here nothing is as parameter because Math.LN2 is not a function but it is a property.
Return Values: It simply return the Value of natural log of 2.

Example:

Input  : Math.LN2
Output : 0.6931471805599453

Explanation: Here simply Value of natural log of 2 i.e, Math.LN2 is shown as output.

Let’s see JavaScript code for Math.LN2 property:

Example 1:

<script>

// Here value of Math.LN2 is printed.

document.write(Math.LN2);

</script>
Output:
```
0.6931471805599453
```

Example 2: Value of natural log of 2 can be printed as in the form of function as shown below.

<script> 
  // function is being called. 
  function get_Value_of_natural_log_of_2() 
  { 
     return Math.LN2; 
  } 
  
  // Calling Function. 
  document.write(get_Value_of_natural_log_of_2()); 
</script> 

Output:

0.6931471805599453

Example 3: Here we consider Math.LN2 as a function but in actual it is a property that is why error as output is being shown.

<script> 
  // Here we consider Math.LN2 as a  
  //function but in actual it 
  // is a property that is why error as 
  // output is being shown. 
  document.write(Math.LN2(12));         
</script> 

Output:

Error: Math.LN2 is not a function

Note: Check console for errors.
