Math operations for BigDecimal in Java
Let us apply the following operations on BigDecimal using the in-built methods in Java −
Addition: add() method Subtraction: subtract() method Multiplication: multiply() method Division: divide() method
Let us create three BigInteger objects −
BigDecimal val1 = new BigDecimal("37578975587.876876989");
BigDecimal val2 = new BigDecimal("62567875598.976876569");
BigDecimal val3 = new BigDecimal("72567875598.376876569");Apply mathematical operations on them −
val1 = val1.add(val2);
System.out.println("Addition Operation = " + val1);
val1 = val1.multiply(val2);
System.out.println("Multiplication Operation = " + val1);
val2 = val3.subtract(val2);
System.out.println("Subtract Operation = " + val2);The following is an example −
Example
import java.math.BigDecimal;
public class Demo {
public static void main(String[] argv) throws Exception {
BigDecimal val1 = new BigDecimal("37578975587.876876989");
BigDecimal val2 = new BigDecimal("62567875598.976876569");
BigDecimal val3 = new BigDecimal("72567875598.376876569");
System.out.println("Value 1 : "+val1);
System.out.println("Value 2 : "+val2);
val1 = val1.add(val2);
System.out.println("Addition Operation = " + val1);
val1 = val1.multiply(val2);
System.out.println("Multiplication Operation = " + val1);
val2 = val3.subtract(val2);
System.out.println("Subtract Operation = " + val2);
val2 = val3.divide(val2,BigDecimal.ROUND_UP);
System.out.println("Division Operation = " + val2);
}
}Output
Value 1 : 37578975587.876876989 Value 2 : 62567875598.976876569 Addition Operation = 100146851186.853753558 Multiplication Operation = 6265975726688315418019.861150364510582502 Subtract Operation = 9999999999.400000000 Division Operation = 7.256787561
