    Question cout


    Could someone please tell me how to format data using cout?

    For example, when using printf if I wanted to print out a floating point number to 2 decimal places I would do:


    Is it possible to do this using cout. The only way I have found is to use sprintf, and give cout the pointer. But surely there is a simpler way.

    Thanks in advance.

    cout << 2.3456764 << endl;

    should out : 2.34.

    keep in mind precision specifies the number of significant digits, not the number of decimal places.
