NAME

std::ios_base::flags - std::ios_base::flags

Synopsis


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


        new formatting setting. It can be a combination of the following constants:


        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
flags - 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
