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 |
