Truncate BigDecimal value in Java

The truncate BigDecimal value in Java, try the following code.

Here, we have taken two BigDecimla values and set the round mode for truncating the decimal values −

Example

 Live Demo

import java.math.BigDecimal;
public class Demo {
   public static void main(String[] argv) throws Exception {
      int decPlaces1 = 3;
      int decPlaces2 = 5;
      BigDecimal val1 = new BigDecimal("37578975587.876876989");
      BigDecimal val2 = new BigDecimal("62567875598.976876569");
      System.out.println("Value 1 : "+val1);
      System.out.println("Value 2 : "+val2);
      // ROUND_DOWN
      val1 = val1.setScale(decPlaces1, BigDecimal.ROUND_DOWN);
      String str1 = val1.toString();
      System.out.println("Result = "+str1);
      // ROUND_UP
      val2 = val2.setScale(decPlaces2, BigDecimal.ROUND_UP);
      String str2 = val2.toString();
      System.out.println("Result = "+str2);
   }
}

Output

Value 1 : 37578975587.876876989
Value 2 : 62567875598.976876569
Result = 37578975587.876
Result = 62567875598.97688
