Convert BigDecimal to Double in Java

You can simple use BigDecimal’s doubleValue() to convert BigDecimal to Double in java.

package org.arpit.java2blog.entry;

import java.math.BigDecimal;

public class BigDecimalToDoubleMain {

public static void main(String[] args) {

BigDecimal bigDecimal = new BigDecimal("22.2345");

Double doubleVal=bigDecimal.doubleValue();

System.out.println("Double value: "+doubleVal);

}

Output:

Double value: 22.2345

BigDecimal to double with 2 decimal places

If you want to restrict double to 2 decimal places, you can use BigDecimal’s setScale() method. You can use RoundMode to specify rounding behavior.

package org.arpit.java2blog.entry;

import java.math.BigDecimal;

import java.math.RoundingMode;

public class BigDecimalToDoubleRoundMain {

public static void main(String[] args) {

double d = 2.3262;

BigDecimal bigDecimal=new BigDecimal(d);

bigDecimal = bigDecimal.setScale(2,RoundingMode.HALF_DOWN);

Double doubleVal=bigDecimal.doubleValue();

System.out.println("Double upto 2 decimal places: "+doubleVal);

// Rounding down

BigDecimal bigDecimal1=new BigDecimal(d);

bigDecimal1 = bigDecimal1.setScale(2,RoundingMode.DOWN);

System.out.println("Double upto 2 decimal places - RoundingMode.DOWN: "+bigDecimal1.doubleValue());

// Rounding up

BigDecimal bigDecimal2=new BigDecimal(d);

bigDecimal2 = bigDecimal2.setScale(2,RoundingMode.UP);

System.out.println("Double upto 2 decimal places - RoundingMode.UP: "+bigDecimal2.doubleValue());

}

Output:

Double upto 2 decimal places: 2.33
Double upto 2 decimal places – RoundingMode.DOWN: 2.32
Double upto 2 decimal places – RoundingMode.UP: 2.33

That’s all about Java BigDecimal to Double.
