How can ı make a function with use floating point numbers(double)???? and I dont want to rounding my numbers and inputs.

Question

as an explain,

#include <iostream>
using namespace std;

int a(double b,double r)
{
if ((b/r)%2==0||((b/r)-1)%2==0)
{
return b/r;
}
else
{
return ((b/r)*r)- 1;
}
}

int main() {
cout << "please enter the share of number";
cin >> x
cout << "please enter the denominator of number";
cin >> y
cout << a(x,y);
return 0;
}

this a function that is giving us exact value function.
but it doesnt work because of rounding number.
what should ı do for this??
