C++ format float number output

Hi,

I don't succeed with formating output for float number, all I want is a list like :
0.00
15.00
12.25
13.56
12.50

from float like :
0.0
15.0
12.25
13.56
12.5

nothing hard but I can not figure out how cout work, I tried :

Code:

cout.precision(3);

cout << showpoint;

cout << 0.0 << "\n" << 15.0 << "\n" << 12.25 << "\n" << 13.56 << "\n" << 12.5 << "\n";

but output is :
0.00
15.0
12.2
13.6
12.5

Any suggestion or where to find man for that will be much apprechated ;)

try
cout.setf(ios::fixed, ios::floatfield);
cout.precision(2);
