Currencies Conversion
<p>On my website, I have stated prizes for specific services in my preferred (primary) currency. I am also willing to accept payments in a few other currencies, but I would like to show converted numerical values to visitors so they won't need to convert them on their own. </p>

<p>This information should get updates instantly when exchange rates changes. It's important that I do NOT need to re-publish the page or entire website. </p>

<p>I would need something like <a href="http://www.mini-itx.com/store/default.asp?c=78&amp;currency=0" rel="nofollow">this  (see Reckoner script)</a> but the script code is not available. Also the conversions should be rounded to nearest 5. </p>

<pre>
1500.03 is rounded to 1500, 
1500.30 is rounded to 1500, 
1500.50 is rounded to 1500, 
1502.49 is rounded to 1500, 
1502.50 is rounded to 1505 (!), 
1504.99 is rounded to 1505, 
1505.01 is rounded to 1505, 
1507.49 is rounded to 1505, 
1507.50 is rounded to 1510
</pre>

<p>Exchange rate from Euro to American Dollar is currently 1 Euro = 1.3229 American Dollar. </p>

<p>So 500 Euro is 661.45 American Dollars but since it's rounded to nearest 5, the conversion shown should be 660 American Dollar. </p>

<p>So the break points are on 2.50 (2.49 is rounded below to nearest 5 so 0 and 2.50 is rounded above to nearest 5 so 5), 7.50, 12.50, 17.50, 22.50, 27.50 and so on.</p>

<p>Is there such a script? How can this be done?</p>
