javascript square root

var x = Math.sqrt(num);

square root javascript

console.log(Math.sqrt(4));     // 2
console.log(Math.sqrt(16));    // 4
console.log(Math.sqrt(64));    // 8
console.log(Math.sqrt(100));   // 10

sqrt javascript

let number = 16
Math.sqrt(number);
//output = 4

Math.sqrt()

console.log(Math.sqrt(4));  // 2
console.log(Math.sqrt(9));  // 3
console.log(Math.sqrt(2));  // 1.4142135623730951

console.log(Math.sqrt(0));  // 0
console.log(Math.sqrt(-0));  // -0
console.log(Math.sqrt(-1));  // NaN

define math.sqrt() method in javascript

// Math.sqrt()

// The Math.sqrt() function returns the square root of a number.

// EXAMPLE : 1
let square_root_of = Math.sqrt(4);
console.log(square_root_of);
// OUTPUT: 2

// EXAMPLE : 2
let square_root_of_1 = Math.sqrt(-9);
console.log(square_root_of_1);
// OUTPUT: NaN (NOT A NUMBER)

// EXAMPLE : 3
let square_root_of_3 = Math.sqrt(8);
console.log(square_root_of_3);
// OUTPUT: 2.8284271247461903

how does square root work javascript

let sqrt = (c, depth = 100, x = 1) =>
    depth <= 0 ? x :
    sqrt(c, depth - 1, x - (Math.pow(x, 2) - c)/(2*x))

console.log(sqrt(2));
