}  I have executed the following commands in the Erlang shell:
}  1) L = [1,2,3,4,5,6,7,8,9,10,11,12,13].
}  2) LB = list_to_binary(L).
}  3) <<A:10/unit:8, B:3/unit:8>> = LB.
}  4) A.
}  5) 4759477275222530853130
}  
}  Please, does anyone know what type is 'A' variable ?
}  'A' variable contains 10 bytes, how can I retrieve each byte from it?
