NumberFormat setMaximumFractionDigits() method in Java with Examples

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

Syntax:

public void setMaximumFractionDigits(int val)

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



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

Below is the implementation of the above function:

        NumberFormat nF
            = NumberFormat.getNumberInstance();
  
        System.out.println("Maximum set initially as: "
                           + nF.getMaximumFractionDigits());
  
        // Set grouping
        nF.setMaximumFractionDigits(100);
  
        // Print the final
        System.out.println("Maximum set finally as: "
                           + nF.getMaximumFractionDigits());
    }
}
