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
