在Java中,通常使用Scanner类来获取输入。 importjava.util.Scanner;publicclassRoundToNearestTen{publicstaticvoidmain(String[]args){// 创建Scanner对象以获取用户输入Scannerscanner=newScanner(System.in);// 提示用户输入一个整数System.out.print("请输入一个整数: ");// 读取用户输入intinput=scanner.nextInt(...

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)=(−...
