DecimalFormat setRoundingMode() method in Java

Last Updated : 01 Apr, 2019

The setRoundingMode() method is a built-in method of the java.text.DecimalFomrat class in Java and is used to set the RoundingMode to be used with this DecimalFormat instance to round-off the decimal digits. Syntax:

public void setRoundingMode(RoundingMode roundingMode)

Parameters: The function accepts a single parameter roundingMode which is the RoundingMode instance to be set for this DecimalFormat instance. Return Value: The function does not returns any value. Below is the implementation of the above function: Program 1:

Java

// Java program to illustrate the
// setRoundingMode() method

import java.text.DecimalFormat;
import java.text.DecimalFormatSymbols;
import java.math.RoundingMode;
import java.util.Currency;
import java.util.Locale;

public class Main {
    public static void main(String[] args)
    {

        // Create the DecimalFormat Instance
        DecimalFormat deciFormat = new DecimalFormat();

        // Set the rounding mode as CEILING
        deciFormat.setRoundingMode(RoundingMode.CEILING);

        System.out.println(deciFormat.format(1234.5555));
    }
}

Output:

1, 234.556

Program 2:

Java

// Java program to illustrate the
// setRoundingMode() method

import java.text.DecimalFormat;
import java.text.DecimalFormatSymbols;
import java.math.RoundingMode;
import java.util.Currency;
import java.util.Locale;

public class Main {
    public static void main(String[] args)
    {

        // Create the DecimalFormat Instance
        DecimalFormat deciFormat = new DecimalFormat();

        // Set the rounding mode as HALF_DOWN
        deciFormat.setRoundingMode(RoundingMode.HALF_DOWN);

        System.out.println(deciFormat.format(1234.5555));
    }
}

Output:

1, 234.555
