What is a better way to convert 5.6789 to 5.68?

[Chris Ben]

Hi all,
the question is as my topic. I know there are a lot methods to do that in Java, but is there any class in Java which can directly do this format conversion?
Thanks a lot
Chris

The DecimalFormat class in the java.text package

double d = 5.6789;
DecimalFormat df = new DecimalFormat(0.00);
String output = df.format(d); // <- equals "5.68"
check the API for the description of the possible output formats.

You could multiply by 100.
Do a Math.round();
Divide by 100.

I already posted following code in one of the forum,
import java.util.* ;
import java.text.* ;
public class test{
public static void main(String s[]){
double formatDouble = 750.1234 ;
NumberFormat converter = NumberFormat.getInstance() ;
converter.setMaximumFractionDigits(2);
converter.setMinimumFractionDigits(2);
System.out.println(converter.format(formatDouble));
}
}
