    Machine limits for integer types.

    Attributes
    ----------
    bits : int
        The number of bits occupied by the type.
    dtype : dtype
        Returns the dtype for which `iinfo` returns information.
    min : int
        The smallest integer expressible by the type.
    max : int
        The largest integer expressible by the type.

    Parameters
    ----------
    int_type : integer type, dtype, or instance
        The kind of integer data type to get information about.

    See Also
    --------
    finfo : The equivalent for floating point data types.

    Examples
    --------
    With types:

    >>> ii16 = np.iinfo(np.int16)
    >>> ii16.min
    -32768
    >>> ii16.max
    32767
    >>> ii32 = np.iinfo(np.int32)
    >>> ii32.min
    -2147483648
    >>> ii32.max
    2147483647

    With instances:

    >>> ii32 = np.iinfo(np.int32(10))
    >>> ii32.min
    -2147483648
    >>> ii32.max
    2147483647
