rounding

[jwilt]

this program is supposed to output rounded numbers for a whole number,
and decimal places for tenth, hundredth, and thousandth, but my output
only outputs whole numbers.

  #include <iostream>
#include <fstream>
#include <cmath>
#include <iomanip>

using namespace std;

int whole(double);
int tenth(double);
int hund(double);
int thous(double);

int main()
{
    int a, b, c, d;
    double num;
    cout << "Input a number to be rounded to the nearest whole number, tenth, hundredth, and thousandth place." << endl;
    cin >> num;
    a = whole(num);
    cout << a << endl;
    b = tenth(num);
    cout << setprecision(1) << fixed << b << endl;
    c = hund(num);
    cout << setprecision(2) << fixed << c << endl;
    d = thous(num);
    cout << setprecision(3) << fixed << d << endl;
    return 0;
}
int whole(double x)
{
    double y = floor (x + .5);
    return y;
}
int tenth(double x)
{
    double y = floor (x * 10 + .5) / 10;
    return y;
}
int hund(double x)
{
    double y = floor (x * 100 + .5);
    y = y / 100;
    return y;
}
int thous(double x)
{
    double y = floor (x * 1000 + .5) / 1000;
    return y;
}

Take a look at your return types.

oh wow, thank you.
