Yes |

No |
~D |
Prints an integer in decimal format. | Yes |
~X |
Prints an integer in hexadecimal format. | No |
~O |
Prints an integer in octal format. | No |
~B |
Prints an integer in binary format. | No |
~F |
Prints a floating-point number in fixed-format. | Partial |
~E |
Prints a floating-point number in exponential format. | No |
~G |
Prints a floating-point number in either fixed-format or exponential format, depending on its value. | No |
~C |
Prints a character. | No |
~P |
Prints "s" if its argument is plural (i.e., not equal to 1); otherwise, prints nothing. | No |

Inserts horizontal tabulation (space padding) to align output. | No |
~<...~> |
Justifies the enclosed text according to specified parameters. | Yes |
~[...~] |
Conditional expression with multiple clauses for case selection. | No |
~{...~} |
Iterates over a list, applying formatting directives to each element. | Yes |
~^ |
Exits the closest enclosing iteration or conditional expression if no more arguments are available. | Yes |
~* |
Consumes an argument without printing it. Useful for skipping arguments. | Yes |
~I |
Indents to a specified column, potentially creating new lines if required. | No |
~_ |
Conditional newline: inserts a newline character if not at the beginning of a line. | No |

No |
~M |
Prints an integer in Roman numerals. | No |
