Multiply it by 100, round it then divide it by 100.

Hi schavalam:

use java.math.BigDecimal class. It is meant for this purpose only (currency fomatting, which as you know goes to 2 decimal points of precision like $23.75)

You must be assigning it to an integral variable such as int or long. Assign to a double or float

CEHJ:  Math.round() returns a long or an int, so can't be used to round a double.

Not like you to miss that :-(

if you just want to print it out,, try using a formatter(it automaticall rounds the value).

import java.text.DecimalFormat;

double d = 1.4567;
DecimalFormat df = new DecimalFormat(".00"); // set it to 2 decimal places
String output = df.format(d);
