Numbers not displaying properly in HTML

I have an HTML page where I am trying to display a currency field from a particular record.

When the number is small I get the number to display 800.0 but if the number is in the millions I get 8.0E+8?

I have found that when the currency is less then 8 digits I get something like 8000000.0 but when an additional digit is added it goes to 8.0E+8

How can I fix this to display like $8,000,000?

Thanks,

Sean

The top part of my HTML page

htmlpage Opportunity_Details(opportunity_idstr, opportunityID)

displayname = "Opportunity Details"

content

<%{

curOpportunity = Opportunity [ID == input.opportunity_idstr.toLong()];

if (!curOpportunity.Read)

{

curOpportunity.Read = true;

}%>

The lower part

<td width=15% class="zc-summary-label">Account Name</td>

<td width=15% class="zc-summary-label">Anticipated Total Contract Value</td>
