__ROR__, __ROL__ in python

• __ROR__ : ROtate Right (circular rotation to the right)
  • __ROR1__ : uint8
  • __ROR2__ : uint16
  • __ROR3__ : uint24
  • __ROR4__ : uint32
• __ROL__ : ROtate Left (circular rotation to the left)
  • __ROL1__ : uint8
  • __ROL2__ : uint16
  • __ROL3__ : uint24
  • __ROL4__ : uint32

def __ROL__(num, count, bits=8):
    return ((num << count) | (num >> (bits - count))) & ((0b1<<bits) - 1)

def __ROR__(num, count, bits=8):
    return ((num >> count) | (num << (bits - count))) & ((0b1<<bits) - 1)
