fmtflags flags() const;	(1)
fmtflags flags( fmtflags flags );	(2)

Manages format flags.

1) returns current formatting setting

2) replaces current settings with given ones.

Parameters

flags

-

new formatting setting. It can be a combination of formatting flags constants.

Formatting flags

Constant	Explanation
dec	use decimal base for integer I/O: see std::dec
oct	use octal base for integer I/O: see std::oct
hex	use hexadecimal base for integer I/O: see std::hex
basefield	dec | oct | hex. Useful for masking operations
left	left adjustment (adds fill characters to the right): see std::left
right	right adjustment (adds fill characters to the left): see std::right
internal	internal adjustment (adds fill characters to the internal designated point): see std::internal
adjustfield	left | right | internal. Useful for masking operations
scientific	generate floating point types using scientific notation, or hex notation if combined with fixed: see std::scientific
fixed	generate floating point types using fixed notation, or hex notation if combined with scientific: see std::fixed
floatfield	scientific | fixed. Useful for masking operations
boolalpha	insert and extract bool type in alphanumeric format: see std::boolalpha
showbase	generate a prefix indicating the numeric base for integer output, require the currency indicator in monetary I/O: see std::showbase
showpoint	generate a decimal-point character unconditionally for floating-point number output: see std::showpoint
showpos	generate a + character for non-negative numeric output: see std::showpos
skipws	skip leading whitespace before certain input operations: see std::skipws
unitbuf	flush the output after each output operation: see std::unitbuf
uppercase	replace certain lowercase letters with their uppercase equivalents in certain output operations: see std::uppercase

Return value

the formatting flags before the call to the function
