Rounding a Decimal to Two Decimal Places in Java

[SS1389]

Hey guys,

I was just wondering what's the easiest way to round a decimal to 2 decimal places in Java? Thanks.

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

e.g.

Java:

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

Yup. That was the method I was looking for. Thanks!

i remember our prof made us do some DecimalFormat function..

Yep Decimal Format is a lot easier to use:

code:

DecimalFormat df = new DecimalFormat("#.##"); System.out.println(df.format(number));

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