fmtflags flags() const;

Returns: The format control information for both input and output.

fmtflags flags(fmtflags fmtfl);

Postcondition: fmtfl == flags().

Returns: The previous value of flags().

Effects: Clears mask in flags(), sets fmtfl & mask in flags().

Returns: The previous value of flags().

void unsetf(fmtflags mask);

Effects: Clears mask in flags().

streamsize precision() const;

Returns: The precision to generate on certain output conversions.

streamsize precision(streamsize prec);

Postcondition: prec == precision().

Returns: The previous value of precision().

streamsize width() const;

Returns: The minimum field width (number of characters) to generate on certain output conversions.

streamsize width(streamsize wide);

Postcondition: wide == width().

Returns: The previous value of width().
