向负无穷方向舍入 ROUND_HALF_DOWN Rounding mode to round towards "nearest neighbor" unless both neighbors are equidistant, in which case round down. 向(距离)最近的一边舍入,除非两边(的距离)是相等,如果是这样,向下舍入, 例如1.55 保留一位小数结果为1.5 ROUND_HALF_EVEN Rounding mode to round towards...
Rounding mode to round towards the "nearest neighbor" unless both neighbors are equidistant, in which case, round towards the even neighbor. 向(距离)最近的一边舍入,除非两边(的距离)是相等,如果是这样,如果保留位数是奇数,使用ROUND_HALF_UP ,如果是偶数,使用ROUND_HALF_DOWN static int Rounding mode ...

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" 该舍入模式也被称为 "Banker's rounding",在统计学上这种模式可以使累计的误差最小4.手动计算IEEE754值示例以常见的 0.1 和 float 为例: 0.1(10)=0.0001100110011...(2)=(−...

Rounding mode to round towards "nearest neighbor" unless both neighbors are equidistant, in which case round up. Behaves as forRoundingMode.UPif the discarded fraction is ≥ 0.5; otherwise, behaves as forRoundingMode.DOWN. Note that this is the rounding mode commonly taught at school. This mode...
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。
Down 1 Rounding mode where the values are rounded towards zero. Ceiling 2 Rounding mode to round towards positive infinity. Floor 3 Rounding mode to round towards negative infinity. HalfUp 4 Rounding mode where values are rounded towards the nearest neighbor. Ties are broken by rounding up. Hal...
