| 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 | |
