Round to nearest, ties away from zero:就近舍入。偏向远离0,即四舍五入。 Directed roundings 定向舍入 Round toward 0:朝向0舍入 Round toward +∞:朝向+∞舍入 Round toward −∞:朝向-∞舍入而在Java 中,默认舍入模式为 RoundingMode.HALF_EVEN,即 "Round to nearest, ties to even" 该舍入模式...
I have a form that needs to multiply two fields and then raound the answer to the nearest ten. Below is what I have, can someone please tell me what I am missing function DoubleRound(nDec, nValue) {// Rounding function - round nValue to nDec decimal places// use a double round to...
Example 1: Round a Number using format public class Decimal { public static void main(String[] args) { double num = 1.34567; System.out.format("%.4f", num); } } Output 1.3457 In the above program, we've used the format() method to print the given floating-point number num to 4 ...

还有一种方式是使用java.text.DecimalFormat,但也存在问题,format采用的舍入模式是ROUND_HALF_DOWN(舍入模式在下面有介绍),比如说4.025保留两位小数会是4.02,因为.025距离”nearest neighbor”(.02和.03)长度是相等,向下舍入就是.02,如果是4.0251那么保留两位小数就是4.03。
mode rounds towards the “nearest neighbor” unless both neighbors are equidistant, in which case, round towards the even neighbor. It is sometimes known as “Banker’s rounding” and is mainly used in the USA. This mode corresponds to theIEEE 754-2019rounding-direction attributeroundTiesToEven....
Rounding to the nearest fraction (i.e. specific decimal place) I'm working on some "star rating" code and I really wanted to round numbers of to the nearest fraction. While the math is really basic, my math skills are rusty and this took me longer to solve than I care to admit. ...
