# JavaScript Math SQRT2 Property

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 Value: 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 1: This example returns the square root of 2 using the Math SQRT2 Property.

## javascript

 `// Here value of Math.SQRT2 is printed.``console.log(Math.SQRT2);`

Output:

`1.4142135623730951`

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

## javascript

 `// 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());`

Output:

`1.4142135623730951`

Example 3: 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

 `// 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());`

Output:

`Error: Math.SQRT2 is not a function`

Example 4: 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.

## javascript

 `// Value of Math.SQRT2 is printed.``console.log(Math.SQRT2);`

Output:

`1.4142135623730951`
