Converting a number to decimal?
I use this bit of Java to convert a number, but I need to break the number (format) into decimal spaces.
Code:
<body onload="euroconv()">
<script language="JavaScript">
function euroconv() {
document.convert.esc.value=Math.round(document.convert.result.value)* 350;
document.convert.temp.value=Math.round(document.convert.esc.value)/ 200.482;
}
</script>
<form name="convert">Pound
<input name="result" value="1"><br>
<input type="hidden" size="6" name="esc">Euro
<input name="temp">
</form>
I need to format "temp" to look like this: 70,000,000 Instead of this: 70000000 Thank's Gerard

java.text.DecimalFormat can be used to format numbers as you
described. For example: Code:
DecimalFormat df = new DecimalFormat("#,##0;(#,##0)");
System.out.println(df.format(70000000));

It seems to make sense, but I dont quite understand how to apply it to my code.
I would be most appreciative if you could elaborate a bit... Thank's Gerard

Since you're posting in this forum I assume you're using JSP.
You'll have to replace your javascript with Java, here's an example of how you can use DecimalFormat: Code:
<%@ page import="java.text.DecimalFormat" %>
<html>
<%!
public String pretty(long val)
{
DecimalFormat df = new DecimalFormat("#,##0;(#,##0)");
return df.format(val);
}
%>
<body>
<%= pretty(70000000) %>
</body>
</html>

I keep my head in the trenches, and I don't look around me.
I am filled with humble sorrow! I was in the wrong forum. I do not know the difference between JSP and JavaScript. I am working with PHP, and I could only find a way to convert the numbers in JavaScript. Do you perhapse have an equal solution for me in JavaScript Thank's Gerard
