Visual C++ :: Range And Incrementation

So there is suppose to be a constant that shows the total number of values to be shown in this range. The user enters two values, lets say userMin is -2 and userMax is 2, it's suppose to add 0.2 to -2 and so on until it reaches 2. It starts doing that up until it reaches -1.0, then it goes to -0.9, -0.7.... etc, It also goes beyond 2.

Code:
#include <iostream>
#include <iomanip>
using namespace std;
int main() {
cout << fixed << setprecision(1);
float userMin;
float userMax;
