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




<script>
  // Here value of SQRT1_2 is printed.
  console.log(Math.SQRT1_2);
</script>


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.  

javascript




<script>
  // function is being called.
  function get_Value_of_square_root()
  {
     return Math.SQRT1_2;
  }
  // function is calling for getting
  // value of square root of 1/2
      console.log(get_Value_of_square_root());
</script>


Output: 

0.7071067811865476

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




<scripe>
  // 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));
</scripe>


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.  

javascript




<script>
  // Value of Math.SQRT1_2 is printed.
  console.log(Math.SQRT1_2);
</script>


Output: 

0.7071067811865476
