text formatting

[riddelrp]

Ok, so I have a dollar amount that is calculated on the page based on amounts entered into textboxes.

The result tends to end up being something like 27.432

how do I round to 2 decimal places for output?

thanks,
Ryan

Also take a look in the php manual for substr function.

[shoop]

var sum= your total

// - this will round it to 2 decimal places
sum=Math.round(sum*100)/100;

// - the rest here makes sure your number displays
// - at least 2 decimal places

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'}
