Display numbers with 2 decimal points using BigDecimal in Java

When working with financial data and other calculations that require a high degree of precision, Java's BigDecimal class is often the go-to choice for developers. One common use case for BigDecimal is to display numbers with a fixed number of decimal points, such as two decimal points for monetary values.

To display a number with two decimal points using BigDecimal, you can use the setScale() method. This method takes two arguments: the number of decimal places to round to, and the RoundingMode to use.

Here's an example:

import java.math.BigDecimal;
import java.math.RoundingMode;

public class Example {
   public static void main(String[] args) {
      BigDecimal number = new BigDecimal("1234.56789");
      BigDecimal rounded = number.setScale(2, RoundingMode.HALF_UP);
      System.out.println(rounded);
   }
}

In this example, we create a BigDecimal object with the value "1234.56789". We then use the setScale() method to round the number to two decimal places using the RoundingMode.HALF_UP mode, which rounds up if the next digit is 5 or greater.

The output of this code would be:

1234.57

By using BigDecimal and the setScale() method with the appropriate RoundingMode, you can ensure that your numbers are displayed with the precision and formatting that you need.
