Java (Precision Problem)

[Pulkit Malhotra]

Hi ,

I'm having a float variable which displays value as 12.3333333333 i want it to show only upto 2 decimal places like 12.33.

Can you please tell me is there any direct function for this in math or util package ?

Thanks in advance.

You'll find interesting things in the BigDecimal class.

So you want to format a number to show only 2 decimal places. You could do that like this:

double value = 12.33333333;
String text = String.format("%.2f", value);
System.out.println(text);

Or you could use java.text.DecimalFormat:

double value = 12.33333333;
DecimalFormat fmt = new DecimalFormat("0.00");
String text = fmt.format(value);
System.out.println(text);
