I want to compile a C++ application and I must not use

#include <iomanip>

Is there any alternative way to do that?

Info: I need the setprecision to be 5

Yes you have the ability to use

cout.precision(5);

This does not require

#include <iomanip>

Note: This will set precision for the whole document.

Example:

cout.precision(5);
cout << f;

You can set the precision() directly on the stream, e.g.:

std::cout.precision(5);
