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);
