I'm working on a program that converts US Dollars to Euros, but it doesn't work well because it won't display any place values past the whole number. So it says 1USD = 1 Euro, which is not accurate, and so on. I need it to display to the 100ths place in order for it to be effective.

 #include <iostream>
 using namespace std;

 int main()
 {
     int z, USD, b, Euro, d;

     cout << "USD-Euro Converter v1.0.\n";
     cout << "Choose what you want to convert:\n";
     cout << "1: United States Dollars -> Euro\n";
     cout << "2: Euro -> United States Dollar\n";

     cin >> z;
     //If Z is neither 1 or 2, the program will continue to Euro -> USD

     if (z == 1)
         {
             cout << "Input USD Amount:\n";
             cin >> USD;

             b = USD * 0.89000;

             cout << USD << " US Dollars are worth " << b << " euros.\n";
             cout << "Dislcaimer: Values are subject to change day to day.\n";
             return 0;
         }
     else
         {
             cout << "Input Euro Amount:\n";
             cin >> Euro;

             d = Euro * 1.12000;

             cout << Euro << " euros are worth " << d << " US Dollars.\n";
             cout << "Dislcaimer: Values are subject to change day to day.\n";
             return 0;
         }

 }
