    decimal place help

    I am new at programming using C++. I am trying to write a program where ouput needs to be formatted to fit certain decimal place criteria. I am using Visual Basic C++. The folowing is just some of the program I wrote:

    cout << fixed << showpoint;

    then some equations, then,

    cout << setprecision(0) << htInches << " inches" << endl;
    cout << setprecision(2) << htMeters << " meters" <<endl;
    cout << setprecision(0) << htCentimeters<< " centimeters" << endl;

    I am racking my brain trying to get this to work. I have been all through the book also. No help at all. Any help I can get would be appreciated. Thank you in advance.

    hmm are you using visual basic or visual c++...hehe..thats my first question..but it seems like you are using visual c++

    here is code:
    Code:
    #include <iostream>
    
    using namespace std;
    
    int main()
    {
    	float x = 1.2345f;
    
    	cout.setf(ios::fixed);
    	cout.precision(3);
    	cout << x << endl;
    
    	return 0;
    
    }
    well it should output only 1.235 since precision is set to 3 it will only out 3 digits after the decimal which is the 4 but it's rounding it up to a 5 because of the 5. hope that helps
