How to add factorial calculation to a WordPress plugin by JavaScript?

I want to add factorial (n!) calculation to Calculated Fields Form WordPress plugin. I found out that module_public.js (in this direction: wp-content\plugins\calculated-fields-form\js\modules\01_mathematical_logical\public) contains the code for math operations and I added these codes, but they did not work (I can make a button for factorial by adding code to module_admin.js and the button works but I can't get the result).
Can anyone help me?
My codes that I added to line 209 in module_public.js:
if(window.FAC == undefined)
{
window.FAC = window.fac = function ()
{
var ans=1;
for (var i = 2; i <= FAC; i++)
ans = ans * i;
return ans;
};
} // End if window.FAC

how to modify below function to read 3 decimal places

I am using tafgeet javascript function to convert numbers into Arabic words, but the problem is that it supports only 2 decimal places, how can I modify the function to make it read 3 decimal places:
It actually translates upto a million on the left hand side, so it would be possible to apply the same methodology on the right side.
I tried to fiddle with it, but it doesn't work. I am posting the original javascript.

Thanks.

Change this:
this.fraction = "" + trimmed[0] + trimmed[1];
To this:
this.fraction = "" + trimmed[0] + trimmed[1] + trimmed[2];
But this is a crude solution you need to do some validations and checks before you deploy this to production

You forgot to close the WarmUpAr funtion,that's why you are getting undefined error

close this function WarmUpAr();
function WarmUpAr() {
var leng = generatelength();
if (leng == 1) {
var cool = twoNumb();
return (cool);
}
if (leng == 2) {
var cool = threNumb();
return (cool);
}
}

The reason threNumb() is failing is because your calling siggna.equals() in all your if statements. twoNumb() works because your using == instead of equals().
Also, in terms of calculating the answer to the equation, your doing it the hard way. In twoNumb() and threNumb() everything between where you set the 'equation' variable and where you return the 'equation' can be replaced with:
ans = eval(equation);

JavaScript function to transform a currency field in words

i found several scripts to do this with ENG/US currency, but I need it in Portuguese language, and its getting hard to find.
I've tried to modify a script to my needs but it is hard.
So, I found this script on web but it dont work too. What is wrong? Uncaught SyntaxError: Unexpected identifier : lin23

I realize that you copied the code as is and pasted into a seperate file. There is a problem with the encoding of some characters. For example, so '-' are incorrectly encoded; so just replace them
i = h.slice(h.length – j, h.length – j + 3)
should be
i = h.slice(h.length - j, h.length – j + 3)
I know you can't see the difference, but the two characters are different.
Have a look at the modified code: http://jsfiddle.net/7P3Vy/

adding autoplay to jquery.roundabout

I have a site I am working on that uses the roundabout from fredhq.com and I would like to make it so it auto plays, I have had a look on their website and can not work out where I need to add the relevant auto play code!

The source you posted doesn't seem to be the latest version of Roundabout.
I just tried with the latest version, and it works perfectly:
$(document).ready(function() {
$('ul').roundabout({
autoplay: true,
autoplayDuration: 1000,
autoplayPauseOnHover: true
});
});
