Setting "setprecision" correctly

Hi although I do something like this

 #include <iomanip>
...
        std::cout<<"Numbers "<<std::setprecision(2)<<numb1<< "  "<<std::setprecision(2)<<numb2<<" "<<std::setprecision(2)<<numb3<<"  "<< std::setprecision(4)<<numb4<<std::endl;

I do get

Numbers  14  1.5e+02 0.0053 & 220

How can I really make set the precision per column to get a consistent format and not this mixture of precision(5) and scientific format?

Use the std::fixed manipulator too which will switch off any reversion to scientific notation:

std::cout << std::fixed /*<< as before from here*/

If you want to switch the scientific notation back on again, then introduce the manipulator std::scientific.
