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 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));    }} |
