/*function
<iomanip>
std::setprecision
setprecision(int n);

1)Set decimal precision

2)Sets the decimal precision to be used to format floating - point values on output operations.

3)Behaves as if member precision were called with n as argument on the stream on which it is inserted / extracted as
a manipulator(it can be inserted / extracted on input streams or output streams).

4)This manipulator is declared in header <iomanip>.*/
