Print float number

The following program prints a float number in different formats:

#include <iostream>
using namespace std;

int main (int argc, char * const argv[]) {
    float number = 123.456;
    
    cout << "number in fixed form = " << number << endl; //default is fixed
    cout << "number in scientific form = " << scientific << number << endl;
    cout.precision(2);
    cout << "number in fixed form with precision 2 = " << fixed << number << endl; 
    cout.precision(3);
    cout << "number in fixed form with precision 3 = " << number << endl;
    cout.precision(4);
    cout << "number in fixed form with precision 4 = " << number << endl;
    cout.precision(5);
    cout << "number in fixed form with precision 5 = " << number << endl;
    
    return 0;
}

Here is the console window:
