关于#java#的问题：

Question

    package AA;
 import java.util.Scanner;
    public class AA {
    public static void main(String[] args) {
    Scanner W=new Scanner(System.in);
     double a, b,c,d,e,f,g,h;
    a=W.nextDouble();
     b=(int)a/10;
    c=(int)(a-b*10)/5;
    d=(int)(a-10*b-5*c)/1;
    e=(double)(a-10*b-5*c-d)/0.5;
    f=(double)(a-10*b-5*c-d-e*0.5)/0.1;
    g=(double)(a-10*b-5*c-d-e*0.5-f*0.1)/0.02;
    h=(double)(a-10*b-5*c-d-e*0.5-f*0.1-g*0.02)/0.01;
    System.out.printf("%.0f 张十元\n",b);
    System.out.printf("%.0f 张五元\n",c);
    System.out.printf("%.0f 张一元\n",d);
    System.out.printf("%.2f 张五角\n",e);
    System.out.printf("%.2f 张一角\n",f);
    System.out.printf("%.2f 张贰分\n",g);
    System.out.printf("%.2f 张壹份\n",h);
    
    
    }
    }
    
 

输入 47.63
结果
4 张十元
1 张五元
2 张一元
1.26 张五角 //为什么输出的是1.26不是1
0 张一角 //为什么输出为0
0.00 张贰分
0.00 张壹份
是不是数据类型转换错误了？
求解惑，感激不尽

给你个参考

 
        Scanner input = new Scanner(System.in);
        double a = input.nextDouble();
        long aLong = Math.round((a * 100));
        long b = aLong / 1000;
        long c = aLong % 1000 / 500;
        long d = aLong % 500 / 100;
        long f = aLong % 100 / 50;
        long j = aLong % 50 / 10;
        long h = aLong % 10 / 2;
        long i = aLong % 2;
        System.out.println(b + " 张十元");
        System.out.println(c + " 张五元");
        System.out.println(d + " 张一元");
        System.out.println(f + " 个五角");
        System.out.println(j + " 个一角");
        System.out.println(h + " 个贰分");
        System.out.print(i + " 个壹分");
