currency conversions...

Hi

I have this code which works fantastically.

Code:

<script type="text/javascript">
exchRate = 1.3; 
function getUSD(price) { 
document.write('(' + price * exchRate + ' &euro;)'); 
}
</script>
<p>Price: &pound;1.40 <script type="text/javascript"> getUSD('1.4'); </script></p>

However, it will require someone changing the exchange rate manually as it changes. So my first question is this... Is there any way I can grab the latest exchange rate from a 3rd party??

Secondly, I need to display the converted price rounded to 2 decimal places. I'm sure I'll be able to work this one out with a little searching around, but any help would be appreciated.

Many thanks.

No, not with Javascript. There are various RSS feeds available.
See: e.g. http://www.xe.com/dfs/ and Google for others.

"Secondly, I need to display the converted price rounded to 2 decimal places."

Code:

<script type="text/javascript">
var exchRate = 1.3; 
function getUSD(price) { 
var np = (price * exchRate).toFixed(2);
document.write('(' + np + ' &euro;)'); 
}
</script>
<p>Price: &pound;1.40 <script type="text/javascript"> getUSD('1.4'); </script></p>

Thanks for that.

OK, so we've established that it's not easy to automate the exchange rate updating...

Is it possible using ASP.net??

Otherwise, what is the best service that I can pay for. Ideally with little or no banners. Is it the XE.com one you mentioned?

Thanks
