You need to use the ``returndatasize`` opcode to check which part of this memory area contains the return data.
The remaining bytes will retain their values as of before the call.
.. note::
With the Paris network upgrade the semantics of ``difficulty`` have been changed.
It returns the value of ``prevrandao``, which is a 256-bit value, whereas the highest recorded
difficulty value within Ethash was ~54 bits.
This change is described in `EIP-4399 <https://eips.ethereum.org/EIPS/eip-4399>`_.
Please note that irrelevant to which EVM version is selected in the compiler, the semantics of
instructions depend on the final chain of deployment.
In some internal dialects, there are additional functions:
