Example

The following example shows the usage of math.BigDecimal.doubleValue() method.

package com.tutorialspoint;

import java.math.*;

public class BigDecimalDemo {

   public static void main(String[] args) {

      // create a BigDecimal object
      BigDecimal bg;

      // create a Double object
      Double d;

      bg = new BigDecimal("1234");

      // assign the converted value of bg to d
      d = bg.doubleValue();

      String str = "Double value of " + bg + " is " + d;

      // print d value
      System.out.println( str );
   }
}

Let us compile and run the above program, this will produce the following result −
