Specifies available formatting flags. It is a bitmask type, the following constants are defined:
| Constant | Explanation | 
| dec | use decimal base for integer I/O | 
| oct | use octal base for integer I/O | 
| hex | use hexadecimal base for integer I/O | 
| basefield | dec|oct|hex|0. Useful for masking operations | 
| left | left adjustment (adds fill characters to the right) | 
| right | right adjustment (adds fill characters to the left) | 
| internal | internal adjustment (adds fill characters to the internal designated point) | 
| adjustfield | left|right|internal. Useful for masking operations | 
| scientific | generate floating point types using scientific notation, or hex notation if combined with fixed | 
| fixed | generate floating point types using fixed notation, or hex notation if combined with scientific | 
| floatfield | scientific|fixed|(scientific|fixed)|0. Useful for masking operations | 
| boolalpha | insert and extract bool type in alphanumeric format | 
| showbase | generate a prefix indicating the numeric base for integer output, require the currency indicator in monetary I/O | 
| showpoint | generate a decimal-point character unconditionally for floating-point number output | 
| showpos | generate a + character for non-negative numeric output | 
| skipws | skip leading whitespace before certain input operations | 
| unitbuf | flush the output after each output operation | 
| uppercase | replace certain lowercase letters with their uppercase equivalents in certain output output operations |
