Module Details
---------------

bitwise_and
~~~~~~~~~~~


.. function:: bitwise_and(evm: ethereum.dao_fork.vm.Evm) -> None
   :noindexentry:

   Bitwise AND operation of the top 2 elements of the stack. Pushes the
   result back on the stack.

   :param evm: The current EVM frame.




.. undocinclude:: /../src/ethereum/dao_fork/vm/instructions/bitwise.py
   :language: python
   :pyobject: bitwise_and

bitwise_or
~~~~~~~~~~


.. function:: bitwise_or(evm: ethereum.dao_fork.vm.Evm) -> None
   :noindexentry:

   Bitwise OR operation of the top 2 elements of the stack. Pushes the
   result back on the stack.

   :param evm: The current EVM frame.




.. undocinclude:: /../src/ethereum/dao_fork/vm/instructions/bitwise.py
   :language: python
   :pyobject: bitwise_or

bitwise_xor
~~~~~~~~~~~


.. function:: bitwise_xor(evm: ethereum.dao_fork.vm.Evm) -> None
   :noindexentry:

   Bitwise XOR operation of the top 2 elements of the stack. Pushes the
   result back on the stack.

   :param evm: The current EVM frame.




.. undocinclude:: /../src/ethereum/dao_fork/vm/instructions/bitwise.py
   :language: python
   :pyobject: bitwise_xor

bitwise_not
~~~~~~~~~~~


.. function:: bitwise_not(evm: ethereum.dao_fork.vm.Evm) -> None
   :noindexentry:

   Bitwise NOT operation of the top element of the stack. Pushes the
   result back on the stack.

   :param evm: The current EVM frame.




.. undocinclude:: /../src/ethereum/dao_fork/vm/instructions/bitwise.py
   :language: python
   :pyobject: bitwise_not

get_byte
~~~~~~~~


.. function:: get_byte(evm: ethereum.dao_fork.vm.Evm) -> None
   :noindexentry:

   For a word (defined by next top element of the stack), retrieve the
   Nth byte (0-indexed and defined by top element of stack) from the
   left (most significant) to right (least significant).

   :param evm: The current EVM frame.
