    It is used for decimal notation (like in floats).

    It says to use a fixed decimal (instead of scientific notation), to use the decimal point, and to have a precision (numbers after decimal point) of 4 decimals.

    Used for output formatting.

    so i assume that it is not necessary to have it included.
    But should i want to use setprecision(*), do i have to include the setiosflag(io::fixed | ios::showpoint.

    ios::showpoint will show the decimal on all floats & doubles

    without showpoint set, 4.00 may display as 4
