Displaying 2 decimal points

[netnow]

Hi,

I am creating a webpage which calculates some dollar totals. However, if the calculation results in the last decimal point being 0 it does not display it. For example, if I add two numbers and the result is 12.70 it is displayed as 12.7 rather than 12.70. Is there any way to overcome this.

thankyou,
Darren.

im not certain this works but it might:

Math.round(variable,2);

This may not be the most elegant solution to the problem but it works.

var sum= your total
sum=Math.round(sum*100)/100;
sum=sum.toString();
var dot=sum.substring(sum.indexOf('.',0)+1,sum.length);
if (sum.indexOf('.',0)==-1){sum=sum+'.00'}
else if (dot.length==1){sum=sum+'0'}

/*
// This part will insert commas
var re = /(-?\d+)(\d{3})/;
var num = sum.toString();
while (re.test(num)) {num = num.replace(re,"$1,$2")}
*/
