# Format number to 2 decimal places in Java

Format number to 2 decimal places in Java | ninjasquad

Quick example to format any type of number – int, long, float, and double to 2 decimal places in Java

## DecimalFormat(“0.00”)

``````import java.text.DecimalFormat;

public class FormatAnyNumber {
private static final DecimalFormat df = new DecimalFormat("0.00");

public static void main(String[] args) {
int num1 = 12345;
long num2 = 12345;
float num3 = 12345.6f;
double num4 = 12345.6789;

System.out.println("int:    " + df.format(num1));
System.out.println("long:   " + df.format(num2));
System.out.println("float:  " + df.format(num3));
System.out.println("double: " + df.format(num4));
}
}
``````
``````Output
int:    12345.00
long:   12345.00
float:  12345.60
double: 12345.68
``````

Points to note&mldr;

1. int and long number has no decimal places, appended “00” at the end for 2 decimal places
2. float number has only one decimal place, appended “0” at the end for 2 decimal places
3. double number has 4 decimal places, rounded to 2 decimal places.

### RoundingMode

By default, `DecimalFormat` use `RoundingMode.HALF_EVEN` for rounding. You can use other rounding modes as follows:-

``````import java.math.RoundingMode;
import java.text.DecimalFormat;

public class FormatAnyNumber {
private static final DecimalFormat df = new DecimalFormat("0.00");

public static void main(String[] args) {
double num = 12345.6789;

df.setRoundingMode(RoundingMode.UP);
System.out.println("double rounding up  : " + df.format(num));
df.setRoundingMode(RoundingMode.DOWN);
System.out.println("double rounding down: " + df.format(num));
}
}
``````
``````Output
double rounding up  : 12345.68
double rounding down: 12345.67
``````
