Width is the amount of bits to generate. If width is larger than the actual amount of bits required to represent number in binary, sign-extension is used. If it's smaller, the representation is trimmed to width bits. Each "bit" is either '\x00' or '\x01'. The MSBit is first. Examples: >>> int_to_bin(19, 5) b'\x01\x00\x00\x01\x01' >>> int_to_bin(19, 8) b'\x00\x00\x00\x01\x00\x00\x01\x01' � r )� bytearray�bytes)�number�width�i�bits� r �A/usr/lib/python3.9/site-packages/elftools/construct/lib/binary.py� int_to_bin s r r )r r �0 �1 � ��0�1Fc C s^ d}d}d}|r8t | d dkr8| dd� } dt| �> }| D ]}|dK }|t | O }q<|| S )z� Logical opposite of int_to_bin. Both '0' and '\x00' are considered zero, and both '1' and '\x01' are considered one.
