Java BigDecimal doubleValue() method

The doubleValue() method of Java BigDecimal class is used to convert the BigDecimal value into a double type. If BigDecimal has very big value represented as a double, it will be converted to Double.NEGATIVE_INFINITY or Double.POSITIVE_INFINITY as appropriate. While conversion, we can lose information about the precision of the BigDecimal value.

Syntax:

Parameter:

Exception:

Returns:

It returns double value converted from BigDecimal.

Example 1

  import java.math.BigDecimal;  public class BigDecimalDoubleValueExample1   {        public static void main(String[] args) {                        // Create BigDecimal object            BigDecimal bdValue;                 // Create double type variable            double dValue;                 bdValue = new BigDecimal(“123”);                 // It will return double type value            dValue = bdValue.doubleValue();                 // Displaying double value            System.out.println(“BigDecimal “+bdValue+” value converted into double is =” +dValue);        }    }    

Test it Now

Output:

BigDecimal 123 value converted into double is =123.0

Example 2

  import java.math.BigDecimal;  public class BigDecimalDoubleValueExample2   {  public static void main(String[] args)   {          // Create BigDecimal object          BigDecimal bdValue;             // Create double type variable          double dValue;             bdValue = new BigDecimal(“113367”);             // It will return double type value          dValue = bdValue.doubleValue();             // Displaying double value          System.out.println(“BigDecimal “+bdValue+” value converted in to double is =” +dValue);  }  }  

Test it Now

Output:

BigDecimal 113367 value converted in to double is =113367.0

Example 3

  import java.math.BigDecimal;  public class BigDecimalDoubleValueExample3   {  public static void main(String[] args)   {          // Create BigDecimal object          BigDecimal bdValue;             // Create double type variable          double dValue;             bdValue = new BigDecimal(“-1120”);             // It will return double type value          dValue = bdValue.doubleValue();             // Displaying double value          System.out.println(“BigDecimal “+bdValue+” value converted in to double is = ” +dValue);  }  }  

Test it Now

Output:

BigDecimal -1120 value converted in to double is = -1120.0
