are required in order to use the following manipulators:
- setprecision: Sets the
number of digits to be printed to the right of the decimal point.
- fixed: Use fixed point

will set the precision to 6 by default.
- showpoint: Causes the
decimal point to be printed even if the precision is set to zero and the
values printed are whole numbers.
- setw: Sets minimum field
(column) width on output. This sets the minimum size of the field. A
larger number will use more columns.
- endl: Writes a newline
('\n') and flushes the buffer.
