float variable won't print desired number of digits

[tigertm64]

I would like the output to print 4.0.
When the program runs it prints 4.
I've tried changing setprecision and changing float type to double, but no difference.

What am I missing here?

#include <iostream>
#include <iomanip>

using namespace std;

float x = 4.0;

int main()
{cout << "Float is " << setprecision(2) << x <<endl;
return 0;
}

Try also using std::fixed.

#include <iostream>
#include <iomanip>

using namespace std;

float x = 4.0;

int main()
{
    cout << "Float is " << setprecision(1) << std::fixed << x <<endl;
    return 0;
}

You probably want to use std::fixed.

cout << "Float is " << fixed << setprecision(1) << x << endl;
