""" categories: Types,int description: ``to_bytes`` method doesn't implement signed parameter. cause: The ``signed`` keyword-only parameter is not implemented for ``int.to_bytes()``. When the integer is negative, MicroPython behaves the same as CPython ``int.to_bytes(..., signed=True)`` When the integer is non-negative, MicroPython behaves the same as CPython ``int.to_bytes(..., signed=False)``. (The difference is subtle, but in CPython a positive integer converted with ``signed=True`` may require one byte more in the output length, in order to fit the 0 sign bit.) workaround: Take care when calling ``to_bytes()`` on an integer value which may be negative.
