Reverse a Number in JavaScript

A sample program in JavaScript that I wrote that will ask the user to enter a number and then our program will reverse the arrangement of numbers given by the user.

If you  have some questions please send me an email at jake.r.pomperada@gmail.com and jakerpomperada@yahoo.com. My mobile number here in the Philippines is 09173084360.


Sample Program Output


Program Listing

<html>
<head>

<body>
  <script>
    
    var reverse_number =0;
var num_value = parseInt(prompt("Enter number: "));

document.write("<br>");
document.write("<h3> Reverse a Number</h3>");
    document.write("<font face='arial' size='3'>");
    document.write("The Original Number is  " + num_value + " .</font> <br>");
    
      while( num_value != 0 )
      {
          reverse_number = parseInt(reverse_number * 10);
          reverse_number = parseInt(reverse_number + (num_value%10));
          num_value = parseInt(num_value/10);
      }
