C++: Controlling the Decimal places to be shown

While dealing with some scientific calculations, I came across a problem that no of digits that were represented after the decimal were not as per the in-file(8 digits). It was only taking 4 digits after the decimal. I had gone through various forums and discovered <iomanip>.

IOMANIP is a header file that is being used to represent the number of decimal places to be used.

#include<iomanip>

void main()
{
        cout<<setiosflags(ios::fixed)<<setprecision(8);
        ......
        ......
        ......
}

Using the above code you can represent as many digits you want to represent after the decimal.
