If an opcode takes arguments (always from the top of the stack), they are given in parentheses.

those marked with ``*`` are special and all others push exactly one item onto the stack (their "return value").
Opcodes marked with ``F``, ``H``, ``B`` or ``C`` are present since Frontier, Homestead, Byzantium or Constantinople, respectively.
