There may be a method for it, but you could just multiply by 100, round it, and then divide by 100.

e.g.
double result = 543.125;
result = Math.Round(result*100)/100;

Yep Decimal Format is a lot easier to use:

[code]DecimalFormat df = new DecimalFormat("#.##");
System.out.println(df.format(number));[/code]

I think the *100, Math.round(), then /100 is much easier. Thank you everyone for your responses.
