# Javascript Square Root, Explained

What is javascript square root? The function to calculate the square root of a number in javascript. This math function can be used in many ways, and knowing how it works will be important for your work as a programmer. If you’re looking for a quick answer on this topic, then read below!

In programming, some of the most common functions are those that perform mathematical operations. One such operation is calculating the square root of a number using javascript. The following tutorial explains how this can be done:

``````var num = prompt("Enter Number");

var result = Math.sqrt(num);

if (result === 0)

else if (result == Infinity)

else if (result == -Infinity)

alert(result + " square root =" + num * result);// displays the answer to the equation. ``````

This can be used as a tool for solving problems that require computing square roots.

## Usage of javascript square root

Square roots are typically used in programming to solve equations that require root finding. For example, if a programmer needs to find the square root of an 800-digit decimal number, they can use javascript’s built-in square root function which will calculate the answer for them with just a few lines of code.

Some javascript developers use the square root function to solve equations that require finding a number’s tenths, hundredths, thousandths, and so on. For example, if someone needs to find out what 1000th of something is (or 100 th of something) they can input an equation like num / 10000 which will then calculate it for them without any hassle.

The square root function is a built-in javascript function which means that it can be used on any computer, regardless of whether or not the browser supports other functions such as trigonometry. It’s often much easier to use one simple line of code and have your answer in just milliseconds than searching through pages and pages of text just to find the answer.

## How javascript square root can use

If you want to use the javascript square root function, you need the Math .sqrt function.

The Math.sqrt function allows you to input any variable or equation, and the result is calculated by javascript within milliseconds of time taken for it to be processed (depending on your internet connection).

## What is Math in JavaScript?

The Math global variable in javascript contains a number of functions that provide support for mathematical computations.

It includes trigonometry, randomization, statistics, and logarithms. This is the reason why JavaScript can be used to calculate square root – because it can use any function from this list.

• In order to run scripts on your browser and make them interactive, you need to add the keyword Script before your line of code – as shown below.
• The script is a javascript function that allows you to do calculations in real time but it can only be run on webpages with scripts enabled.
``````var squareRoot = Math .sqrt ( 16 );

console .log ( squareRoot );

console .log ( "The first 16 roots of unity, in order:" )

for ( var i = 0 ; i <= 15 ; ++i) { console .log ([ Math .sqrt (I), ' \ n' ]); } ``````
• So what is the problem with this code? Well, it will never end because the square root of 16 will never be a whole number.
• Here is what we need to do:
``````var sqrt16 = Math .sqrt ( 16 );

console .log ( "The first 16 roots of unity, in order:" ) // Logs [0, 0.2588235294117``````

## Cons and Pros of using Math variable

• The Math variable is a global object and its use can be seen by the javascript interpreter.
• Math objects have many methods that enable you to do calculations in real-time but they only work on web pages with scripts enabled.

## Conclusion :

Learning how to calculate square roots is a valuable skill, but it can also be difficult. With the help of this article’s explanations and examples, you should have no problem understanding the core principles behind Javascript Square Root calculations.
