The Math.SQRT1_2 is a property in JavaScript which is simply used to find the value of square root of 1/2, whose value is approximately 0.707106
That is,

√ (1/2)  = 0.707106

Syntax:

`Math.SQRT1_2;`

Return Values: It simply returns the value of the square root of 1/2, whose value is approximately 7071.

Below is the example of the Math SQRT1_2 Property.

Example:

## javascript

 ``

Output:

`0.7071067811865476`

Example: Here simply value of square root of 1/2 is shown as output.

```Input : Math.SQRT1_2
Output : 0.7071067811865476```

More codes for the above property are as follows:

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

Program 2: Here we consider Math.SQRT1_2 is a function but in actual it is a property which is why the error as output is being shown.

## javascript

 `` `  ``// Here we consider Math.SQRT1_2 as a function` `  ``// but in actual it is a property that is why ` `  ``// error as output is being shown.` `  ``console.log(Math.SQRT1_2(12));` ``

Output:

`Error: Math.SQRT1_2 is not a function`

Program 3: It will find the value of the square root of 1/2 which is done with the help of this property. In mathematics, it needed a lot.
