你好，关于您的问题 ，java用对话框输入一个float小数答案是：package biji;import java.util.scanner;public class demo17 { public static void main(String[ ] args) {scanner input =new Scanner(System.in);system.out.printf("请输入一个小数:");double num1 = input.nextDouble();int num2...
AI代码解释 m=int(input())n=m*(m-1)//2*(m-2)//3*(m-3)//4print(n) 此时,我才想起来python内部将“/”默认为float除法,根据计算机给予的float类型的精度本身就是小于c++中的unsigned long long类型 查阅为2的53次方,自然不满足题意,float就会取一个近似值(这不糊弄人吗?[doge]) 上边代码应该时...
在java中,简单的浮点类型float和double是不能够进行运算。我们先看下面的两个程序代码: 代码一: import java.util.Scanner; class Circle { double radius; static final double PI=3.14; public Circle(){this.radius=0;} public Circle(double r){this.radius=r;} ...
