How to convert negative numbers to positive numbers in BigDecimal in Java?

In Java, you can use the abs() method to convert the value of a BigDecimal object to a positive number. An example is shown below:

import java.math.BigDecimal;

public class Main {
    public static void main(String[] args) {
        BigDecimal number = new BigDecimal("-123.45");
        
        // 使用abs()方法将负数转为正数
        BigDecimal positiveNumber = number.abs();
        
        System.out.println("原始值：" + number);
        System.out.println("转换为正数：" + positiveNumber);
    }
}

In the example above, we created a BigDecimal object ‘number’ with a value of -123.45. We then used the abs() method to convert it into a positive number and stored the result in ‘positiveNumber’. Finally, we printed out the original value and the converted positive value. The result is as follows:

原始值：-123.45
转换为正数：123.45
