  int precision( int np );
  int precision() const;
 
  Parameter   Description
 
  <np>        An integer that indicates the number of significant digits
              or significant decimal digits to be used for floating-point
              display.
 
  Remarks
 
  The first overloaded precision function sets the stream's internal
  floating-point precision variable to <np> and returns the previous
  value. The default precision is six digits. If the display format is
  scientific or fixed, then the precision indicates the number of digits
  after the decimal point. If the format is automatic (neither floating
  point nor fixed), then the precision indicates the total number of
  significant digits.
 
  The second function returns the stream's current precision value.
