爪哇岛四分之一/二分之一/五分之一/便士的回报率变化

Question

我需要帮助来完成我正在尝试做的小项目。它没有正确返回您需要的硬币数量，输出应该是这样的：

购买金额=23.06投标现金=30.00所需硬币数量： 94美分=3个季度1个一角硬币1个镍币4个便士

    ConsoleIO keyboard = new ConsoleIO( );
    double cashPaid, purchaseAmount, temp;
    int change; 
    int quarters, dimes, nickels, pennies;
    System.out.println("------------START--------------");
    System.out.print("Please enter total amount: $");
    purchaseAmount = keyboard.readDouble();

    System.out.print("Enter amount paid: $");
    cashPaid = keyboard.readDouble();

    temp = (cashPaid - purchaseAmount);
    System.out.println("CHANGE: $" + temp + "\n");
    double coins = temp;

    quarters = (int)(temp/25);
    coins %= 25;
    dimes = (int)(coins/10);
    coins %= 10;
    nickels = (int)(coins/5);
    coins %= 5;
    pennies = (int)(coins/1);
    coins %= 1;

    System.out.println("Quarters = " + quarters + "\nDimes = " + dimes + "\nNickels = " + nickels + "\nPennies = " + pennies);

    System.out.println("-------------END---------------");

你的临时工是美元。它应该以美分为单位。
