JavaScript - Create Specific Number Output Based Upon Internal Calcs

Noob here!
I'm doing a little project where i need to take a number (lets say 6), and then I need to find out witch numbers 6 can divided with that equals to a whole number. Any ideas how i can do that?

This is what i got in my mind so far:

myNum/num === wholeNumber

I then need a variable "num" that count all whole numbers from 0 to myNum
and a variable "wholeNumber" that works as all whole numbers from 0 to myNum.

I really hope you can help me out, thanks

Hi does anyone know how to output a reformated number to a form?? This is what I have so far:

Code:

if (!document.userSurvey.phone.value)
    {
        alert("Phone number missing. Please enter a valid phone number to continue.");
        document.userSurvey.phone.focus();
        return false;	  
    }
    else
    {
        var numbersOnly = "";
        var chars = "";
        var phoneNo = document.userSurvey.phone.value;

        for (i = 0; i < phoneNo.length; i++)
        {
            chars = phoneNo.substring(i,i+1);
          
            if (chars >= "0" && chars <= "9")
            {
                numbersOnly = numbersOnly + chars;
            }
        }

        if (numbersOnly.length != 13)
        {
            alert("Incorrect phone number format.You must enter 13 numbers.");
            document.userSurvey.focus();
            return false;
        }
        else
        {
            var areacode = numbers.substring(0,2);
            var leading0 = numbersOnly.substring(2,3);
            var exchange = numbersOnly.substring(3,5);
            var ext1 = numbersOnly.substring(5,9);
            var ext2 = numbersOnly.substring(9);
            var newNumber =( "+" + areacode + " " +"(" + leading0 + ")" +       exchange + " " + ext1 + "-" + ext2);

Hi guys,
I am new to java, I am having trouble on outputting the num2 on the screen. I could not see any errors indicated the problem on the program(Eclipse). However, the program just miss scan the num2. I was trying to sort the number and output them from smallest to largest.
Any suggestion would be helpful and appreciated!

Well after much trial and error I come asking for help. I am trying to write a greasemonkey script that scans a page for all the values between certain <td> tags. When I used firebug it shows what I am looking for as
<td class="username">THEUSERNAME</td>
but when I view the source it just shows up as
<td>THEUSERNAME</td>
I want to create an array of the 100 <td>'s on the page that pertain to usernames but none of the other <td>'s

I created a test page that mimicked the code, what I thought origionally, to be so I could test my script with ease. And it worked when there was an actually <td class="username">

This is what I have so far:

Code:

// ==UserScript==
//
//Displayable Name of your script 
// @name           EXAMPLE 
//
// brief description
// @description    EXAMPLE 
//
//URI (preferably your own site, so browser can avert naming collisions
// @namespace      http://something.com
//
// Your name, userscript userid link (optional)   
// @author         ME
//
//Version Number
// @version        1.0
//
// Urls process this user script on
// @include        http://example.com
// ==/UserScript==


var test = document.getElementsByClassName('username');

alert(test.length);
test[5].style.color="yellow"; //Just to see if it actually worked

How would I go about creating a random number between 1-50 that COULD include whole numbers, decimals to the tenth, hundredth and the thousandth place?

Ex) 2.145, 3, 5.8, 41.002, 10.12, 7, 18.023, 33.2

Also, if the only way to do it is to put trailing zeros to the thousandth place that's fine as well

ex) 2.145, 3.00, 5.800, 41.002, 10.120, 7.00, 18.023, 33.200
