    Help with temperature conversion Chart

    I am working on a temp chart conversion. We have the the conversion from Celsius to Fahreneheit rounded to whole numbers but the conversion from Fahrenheit to Celsius keep putting decimals out. I need it to output whole numbers.
    Here is the code:
    #include <iostream>
    #include <iomanip>
    #include <fstream>
    using namespace std;

    int main()
    {
    ofstream outFile ("ass3.run");
    const int LOWER = 0;
    const int UPPER = 400;
    const int STEP = 10;

    int FARR = LOWER;
    float Celsius;

    /* Print table heading */
    outFile <<setw(19);
    outFile << "Fahrenheit";
    outFile <<setw(12);
    outFile << "Celsius";
    outFile <<setw(20);
    outFile << endl;

    /* print table from LOWER to UPPER */
    for (FARR = LOWER ; FARR <= UPPER ; FARR += STEP)
    {
    int Fahrenheit (int);
    outFile <<setw(15);
    outFile << FARR;
    Celsius = (float(5)/float(9)) * (FARR - 32);
    outFile <<setw(15);
    outFile << Celsius;
    outFile <<setw(15);
    outFile <<endl;
    }
    const int RETARD =0;
    const int STUPID =200;
    const int ASS = 5;

    int CELS = RETARD;
    float FAR;
    outFile <<setw(19);
    outFile <<endl<<endl;
    outFile << "Celsius";
    outFile <<setw(15);
    outFile << "Fahrenheit";
    outFile <<setw(20);
    outFile << endl;

    for (CELS = RETARD; CELS <= STUPID ; CELS += ASS)
    {
    int Celsius (int);
    outFile <<setw(15);
    outFile << CELS;
    FAR = (float(9)/float(5) * (CELS) + 32);
    outFile <<setw(15);
    outFile << FAR;
    outFile <<setw(15);
    outFile <<endl;
    }

    return 0;
    }[CODE]
    This is the output we keep getting:

    Fix the code tags please.

    They go AROUND your code - its not enough just to put [code] in there and hope
    If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
    If at first you don't succeed, try writing your phone number on the exam paper.
