# Number to Bin Converter Using Javascript

### Language

In this tutorial, I am going to teach you how to make a number to binary converter. You can also convert it to hexadecimal and octal representation. To use this simple code just download the source code below.

#### Instructions

First, we will be writing our html code.
`<b>Insert Decimal Number: </b><input type = "text" name = "deci" id = "deci" size = "15" maxlength = "15" /><input type="button" value="Convert!" onclick="dec2bin()" /><br><br><div id = "result"></div>`
This will be our javascript code.
`<script type = "text/javascript"> function dec2bin() {var x = document.getElementById("deci").value;if ((/[^0-9]/g.test(x)) || x == "") {alert ("You must enter an integer decimal number!");document.getElementById("deci").value = "";document.getElementById("deci").focus();return false;}x = parseInt(x);var bin = x.toString(2);var hex = x.toString(16).toUpperCase();var octal = x.toString(8);  var figs = "The binary representation of " + x + " is " + bin + "<br>";figs = figs + "The hexadecimal representation of " + x + " is " + hex + "<br>";figs = figs + "The octal representation of " + x + " is " + octal + "<br>"; document.getElementById("result").innerHTML = figs;}</script>`
Finally, you have created a simple converter of number to binary. For more suggestions, queries and questions, feel free to comment below.
