Working with BigDecimal values in Java

The java.math.BigDecimal class provides operations for arithmetic, scale manipulation, rounding, comparison, hashing, and format conversion.

Two types of operations are provided for manipulating the scale of a BigDecimal −

• scaling/rounding operations
• decimal point motion operations

The following are some of the constructors of the BigDecimal values −

The following is an example −

Example

 Live Demo

import java.math.BigDecimal;
public class Demo {
   public static void main(String[] argv) throws Exception {
      BigDecimal val1 = new BigDecimal("37578975.8768");
      BigDecimal val2 = new BigDecimal("62567878.9768");
      BigDecimal val3 = new BigDecimal("72567874.3768");
      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 : 37578975.8768
Value 2 : 62567878.9768
Addition Operation = 100146854.8536
Multiplication Operation = 6265976294387200.48179648
Subtract Operation = 9999995.4000
Division Operation = 7.2568
