• Last Updated : 10 Jul, 2020

Below is the example of the Math SQRT1_2 Property.

• Example:
 ``
• Output:
```0.7071067811865476
```

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 square root of 1/2, whose value is approximately 7071.

Below example illustrates the Math SQRT1_2 property in JavaScript.

• 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 as in the form of function as shown below.

 ``

Output:

`0.7071067811865476`

Program 2: 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.

 ```  ``// 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.``  ``document.write(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.

 ``

Output:

`0.7071067811865476`
