NumberFormat setMinimumFractionDigits() method in Java with Examples

  • Last Updated : 01 Apr, 2019

The setMinimumFractionDigits() method is a built-in method of the java.text.NumberFormat which sets the minimum number of digits allowed in the fraction portion of a number.If the new value for minimumFractionDigits is less than the current value of maximumFractionDigits, then maximumFractionDigits will also be set to the new value.

Syntax:

public void setMinimumFractionDigits(int val)

Parameters: The function accepts a mandatory parameter val which specifies the minimum value to be set.

Return Value: The function returns nothing, hence has a return type void.

Below is the implementation of the above function:

Program 1:




// Java program to implement
// the above function
  
import java.text.NumberFormat;
import java.util.Locale;
import java.util.Currency;
  
public class Main {
    public static void main(String[] args)
        throws Exception
    {
  
        NumberFormat nF
            = NumberFormat.getNumberInstance();
  
        System.out.println("Minimum set initially as: "
                           + nF.getMinimumFractionDigits());
  
        // Set grouping
        nF.setMinimumFractionDigits(100);
  
        // Print the final
        System.out.println("Minimum set finally as: "
                           + nF.getMinimumFractionDigits());
    }
}
Output:
Minimum set initially as: 0
Minimum set finally as: 100

Program 2:




// Java program to implement
// the above function
  
import java.text.NumberFormat;
import java.util.Locale;
import java.util.Currency;
  
public class Main {
    public static void main(String[] args)
        throws Exception
    {
  
        NumberFormat nF
            = NumberFormat.getNumberInstance();
  
        System.out.println("Minimum set initially as: "
                           + nF.getMinimumFractionDigits());
  
        // Set grouping
        nF.setMinimumFractionDigits(7998);
  
        // Print the final
        System.out.println("Minimum set finally as: "
                           + nF.getMinimumFractionDigits());
    }
}
Output:
Minimum set initially as: 0
Minimum set finally as: 7998
