条件运算符的输出无效

Question

我写了一个程序并且结果有问题。当我输入一些数字时，例如43.01，条件运算符忽略该语句为真并给出错误输出（0美分），问题出在哪里？

int main()
{
    double money_amount;
    cout << "Enter money amount. For example: 3.59\n";
    cin >> money_amount;
    int dollar_amount = money_amount;
    double cent_amount = money_amount - dollar_amount;
    cout << cent_amount << "\n"; // to make sure that there is 0.01
    dollar_amount == 1 ? cout << "You have 1 dollar\n" : cout << "You have " << dollar_amount << " dollars\n";
    cent_amount == 0.01 ? cout << "You have 1 cent\n" : cout << "You have " << floor(cent_amount*100) << " cents\n"; // here is the problem
}
