# JavaScript | Math.LOG10E property

The Math.LOG10E is a property in JavaScript which is simply used to find the value of base 10 logarithm of e, where e is an irrational and transcendental number approximately equal to 2.718
Syntax:

`Math.LOG10E;`

Parameters:

• Here nothing is as parameter because Math.LOG10E is not a function but it is a property.
• Return Values:

• It simply return the value of base 10 logarithm of e.

Example:

```Input:
Math.LOG10E
Output:
0.4342944819032518
```

Explanation:
Here simply value of base 10 logarithm of e is shown as ouput.

Let’s see JavaScript code for Math.LOG10E property:
Code #1:

 `// Here value of Math.LOG10E is printed. ` `console.log(Math.LOG10E); `

/div>

Output:

`> 0.4342944819032518`

Code #2:
Value of base 10 logarithm of e can be printed as in the form of function as shown below.

 `// function is being called. ` `function` `get_Value_of_base_10_lagarithm_of_e() ` `{ ` `    ``return` `Math.LOG10E; ` `} ` `// function is calling. ` `console.log(get_Value_of_base_10_lagarithm_of_e()); `

Output:

`> 0.4342944819032518`

Errors and Exceptions:

1. Here we consider Math.LOG10E as a function but in actual it is a property that is why error as output is being shown.
 `// Here we consider Math.LOG10E as a function but in actual it ` `// is a property that is why error as output is being shown. ` `console.log(Math.LOG10E(12)); `

Output:

`Error: Math.LOG10E is not a function`

Application:

• Whenever we need to find the value of base 10 logarithm of e that time we take the help of this property.In mathemaatics it needed a lot.
Let’s see JavaScript program on this application:

 `// Value of Math.LOG10E is printed. ` `console.log(Math.LOG10E); `

Output:

`> 0.4342944819032518`
