The following type codes are defined: \begin{tableiii}{|c|c|c|}{code}{Typecode}{Type}{Minimal size in bytes} \lineiii{'c'}{character}{1} \lineiii{'b'}{signed integer}{1} +\lineiii{'B'}{unsigned integer}{1} \lineiii{'h'}{signed integer}{2} +\lineiii{'H'}{unsigned integer}{2} \lineiii{'i'}{signed integer}{2} +\lineiii{'I'}{unsigned integer}{2} \lineiii{'l'}{signed integer}{4} +\lineiii{'L'}{unsigned integer}{4} \lineiii{'f'}{floating point}{4} \lineiii{'d'}{floating point}{8} \end{tableiii} The actual representation of values is determined by the machine architecture (strictly speaking, by the C implementation). The actual -size can be accessed through the \var{itemsize} attribute. +size can be accessed through the \var{itemsize} attribute. The values +stored for \code{'L'} and \code{'I'} items will be represented as +Python long integers when retrieved, because Python's plain integer +type can't represent the full range of C's unsigned (long) integers.
