Java get decimal value

     

We can also get the decimal value in the specified format as we wish by calling DecimalFormat class. It will format a long value to the specified string pattern.

DecimalFormat dec = new DecimalFormat("###.##"); 
System.out.println(dec.format(12345.6789)); 

Above lines of code prints decimal value 12345.6789 in the 12345.68 format. Also we can print this decimal value in other different formats by defining the decimal format pattern. Here is the full example code for GetDecimalValue.java as follows:

 

GetDecimalValue.java

import java.util.*;
import java.text.*;

public class GetDecimalValue
{
  public static void main(String args[]) {
  // Decimal Value in the 12345.68 format
  // By rounding the last digit
  DecimalFormat dec = new DecimalFormat("###.##");
  System.out.println(dec.format(12345.6789))

  // Decimal Value in the 12345.679 format
  // By rounding the last digit
  dec = new DecimalFormat("###.###");
  System.out.println(dec.format(12345.6789))

  // Decimal Value in the 12345.7 format
  // By rounding the last digit
  dec = new DecimalFormat("###.#");
  System.out.println(dec.format(12345.6789));
  }
}

Output:

C:\javaexamples>javac GetDecimalValue.java

C:\javaexamples>java GetDecimalValue
12345.68
12345.679
12345.7
