JavaScript Square Root: Math.sqrt() Method
Last updated on: by Digamber
To get the square root of any number we use JavaScript Square Root –
Math.sqrt()
method. JavaScript offers many powerful methods to solve mathematical problems. In this tutorial, I will teach you how to use the Sqrt() method. Understand the JavaScript Square Root Method
Math.sqrt(number)
- Number: It has to be a valid numerical value.
- If you pass the positive number, the
Math.sqrt()
method will return the square root for the specified value. - If you pass the negative or not a valid number, then you’ll get the NAN value.
- If you don’t pass the argument in SQRT() method, it will return 0.
JavaScript Math.sqrt() Examples:
Let us calculate the square root of the given below values using JavaScript square root method.
let a = Math.sqrt(0);
// output: 0
let b = Math.sqrt(1);
// output: 1
let c = Math.sqrt(10);
// output: 3.1622776601683795
let d = Math.sqrt(-12);
// output: null
let e = Math.sqrt(9);
// output: 3
let f = Math.sqrt(-9);
// output: null
let g = Math.sqrt(13.5);
// output: 3.6742346141747673
let h = Math.sqrt('avengers');
// output: null
let i = Math.sqrt(null);
// output: 0
