NumberFormat setMinimumFractionDigits() method in Java with Examples

Last Updated : 11 Jul, 2025
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 
// 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 
// 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
