BigDecimal.ROUND_FLOOR

ROUND_FLOOR is a rounding mode constant in the BigDecimal class in Java. It represents rounding towards negative infinity. When the ROUND_FLOOR mode is used, the value will be rounded down to the next whole number or the nearest lower value.

Here's an example of how to use ROUND_FLOOR with BigDecimal in Java:

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

public class Main {
    public static void main(String[] args) {
        BigDecimal value = new BigDecimal("3.14159");
        BigDecimal roundedValue = value.setScale(2, RoundingMode.FLOOR);
        System.out.println("Rounded value: " + roundedValue);
    }
}

Output:
Rounded value: 3.14

In this example, the value 3.14159 is rounded down to 3.14 using the ROUND_FLOOR mode.
