首先,我们定义了一个静态方法roundToTwoDecimalPlaces,该方法接受一个double类型的参数number,并返回保留两位小数四舍五入后的结果。 在roundToTwoDecimalPlaces方法中,我们使用了Math.round方法将number乘以100后进行四舍五入,并将结果除以100.0得到保留两位小数四舍五入后的结果。 然后,我们在main方法中定义了一个doubl...
The result should be rounded to 2 decimal places If and only if it is not an integer. Sample Input 4 + 1 2 - 1 2 * 1 2 / 1 2 Sample Output 3 -1 2 0.50 [java] view plain copy import java.util.Scanner; public class Main { public static void main(String[] args) { Scanner ...
This Java tutorial taught us to round off a given floating point number to 2 decimal points using different techniques. We learned to use the Decimal class (recommended),Math,PrecisionandDecimalFormatclasses. As a best practice, always use theDecimalclass with rounding mode set toHALF_EVEN. Happy...

For each case, print the operation result. The result should be rounded to 2 decimal places If and only if it is not an integer. Sample Input 4 + 1 2 - 1 2 * 1 2 / 1 2 Sample Output 3 -1 2 0.50 import java.util.Scanner; ...
We specify a new pattern withapplyPattern. This pattern adds zeros to decimal places, if they are empty. Grouping digits The,format character is used for grouping of digits. Main.java import java.text.DecimalFormat; void main() { double n = 2_125_405.30; ...
