任意の金額の紙幣と硬貨の数を取得

Question

任意の金額のために最適化された紙幣と硬貨を返すシステムを作りたいと思います。ここで

はしばらくの間、私のコードです：まあ、それはほとんど正しいです

public static void main(String[] args) throws IOException { 
    BufferedReader br = new BufferedReader(
      new InputStreamReader(System.in)); 
    double amount = Double.parseDouble(br.readLine()); 
    if (amount > 0 && amount < 1000000.00) { 
     // ############################# BILLS ############################ 
     double rest100 = amount/100; 
     double rest50 = amount % 100; 
     double rest20 = rest50 % 50; 
     double rest10 = rest20 % 20; 
     double rest5 = rest10 % 10; 
     double rest2 = rest5 % 5; 

     // ############################ COINS ############################    
     double rest01 = rest2 % 2; 
     double rest050 = rest01 % 1; 
     double rest025 = rest050 % .5; 
     double rest010 = rest025 % 25; 
     double rest005 = rest010 % .1; 
     double rest001 = rest005 % .05; 

     System.out.println("BILLS:\n" 
      + (int) rest100 
      + " bill(s) of 100.00\n" 
      + (int) rest50/50 
      + " bill(s) of 50.00\n" 
      + (int) rest20/20 
      + " bill(s) of 20.00\n" 
      + (int) rest10/10 
      + " bill(s) of 10.00\n" 
      + (int) rest5/5 
      + " bill(s) of 5.00\n" 
      + (int) rest2/2 
      + " bill(s) of 2.00\n" 
      + "COINS:\n" 
      + (int) (rest01/1) 
      + " coin(s) of 1.00\n" 
      + (int) (rest050/.5) 
      + " coin(s) of 0.50\n" 
      + (int) (rest025/.25) 
      + " coin(s) of 0.25\n" 
      + (int) (rest010/.1) 
      + " coin(s) of 0.10\n" 
      + (int) (rest005/.05) 
      + " coin(s) of 0.05\n" 
      + (int) (rest001/.01) 
      + " coin(s) of 0.01"); 
    } 
} 

、法案は完璧な作業している、私の問題はコインです。ここで

は、いくつかの入力です：

• 576.73 //印刷正しく
• 8.45 //印刷誤っ
• 9.45 //印刷誤っ、下記をご覧：

実際の出力：

BILLS: 
0 bill(s) of 100.00 
0 bill(s) of 50.00 
0 bill(s) of 20.00 
0 bill(s) of 10.00 
1 bill(s) of 5.00 
2 bill(s) of 2.00 
COINS: 
0 coin(s) of 1.00 
0 coin(s) of 0.50 
1 coin(s) of 0.25 
4 coin(s) of 0.10 
0 coin(s) of 0.05 
4 coin(s) of 0.01 

Expecテッド出力：

BILLS: 
0 bill(s) of 100.00 
0 bill(s) of 50.00 
0 bill(s) of 20.00 
0 bill(s) of 10.00 
1 bill(s) of 5.00 
2 bill(s) of 2.00 
COINS: 
0 coin(s) of 1.00 
0 coin(s) of 0.50 
1 coin(s) of 0.25 
2 coin(s) of 0.10 
0 coin(s) of 0.05 
0 coin(s) of 0.01 

PS：それは今より質問が大きくできるようになる、しかし、あなたが必要な場合は、私が投稿することができますので、私はすべての期待される出力を掲載しません。前もって感謝します。

次のバージョンのコードは、ご使用の要件に応じて動作します。モジュラス演算ではdoubleを使用しないでください。

CODE：

public static void main(String[] args) throws NumberFormatException, IOException { 
    BufferedReader br = new BufferedReader(
      new InputStreamReader(System.in)); 
    double amount = Double.parseDouble(br.readLine()); 
    amount= Math.round(amount*100);  
    if (amount > 0 && amount < 1000000.00) {    
     // ############################# BILLS ############################ 
     double rest100 = amount/10000; 
     double rest50 = amount % 10000; 
     double rest20 = rest50 % 5000; 
     double rest10 = rest20 % 2000; 
     double rest5 = rest10 % 1000; 
     double rest2 = rest5 % 500; 

     // ############################ COINS ############################    
     double rest01 = rest2 % 200; 
     double rest050 = rest01 % 100; 
     double rest025 = rest050 % 50; 
     double rest010 = rest025 % 25; 
     double rest005 = rest010 % 10; 
     double rest001 = rest005 % 5; 

     System.out.println("BILLS:\n" 
      + (int) Math.floor(rest100) 
      + " bill(s) of 100.00\n" 
      + (int) (rest50/5000) 
      + " bill(s) of 50.00\n" 
      + (int) (rest20/2000) 
      + " bill(s) of 20.00\n" 
      + (int) (rest10/1000) 
      + " bill(s) of 10.00\n" 
      + (int) (rest5/500) 
      + " bill(s) of 5.00\n" 
      + (int) (rest2/200) 
      + " bill(s) of 2.00\n" 
      + "COINS:\n" 
      + (int) (rest01/100) 
      + " coin(s) of 1.00\n" 
      + (int) (rest050/50) 
      + " coin(s) of 0.50\n" 
      + (int) (rest025/25) 
      + " coin(s) of 0.25\n" 
      + (int) (rest010/10) 
      + " coin(s) of 0.10\n" 
      + (int) (rest005/5) 
      + " coin(s) of 0.05\n" 
      + (int) (rest001/1) 
      + " coin(s) of 0.01"); 
    } 

OUTPUT：

9.45 
BILLS: 
0 bill(s) of 100.00 
0 bill(s) of 50.00 
0 bill(s) of 20.00 
0 bill(s) of 10.00 
1 bill(s) of 5.00 
2 bill(s) of 2.00 
COINS: 
0 coin(s) of 1.00 
0 coin(s) of 0.50 
1 coin(s) of 0.25 
2 coin(s) of 0.10 
0 coin(s) of 0.05 
0 coin(s) of 0.01 

Answer 2

100を掛けてセントで計算します。
