std::ios_base::flags
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
