# pandas.api.types.is_int64_dtype

pandas.api.types.is_int64_dtype(arr_or_dtype)

  Check whether the provided array or dtype is of the int64 dtype.

  Deprecated since version 2.1.0: is_int64_dtype is deprecated and will be removed in a future version. Use dtype == np.int64 instead.

  Parameters:
    arr_or_dtypearray-like or dtype

      The array or dtype to check.

  Returns:
    boolean

      Whether or not the array or dtype is of the int64 dtype.

  Notes

  Depending on system architecture, the return value of is_int64_dtype( int) will be True if the OS uses 64-bit integers and False if the OS uses 32-bit integers.

  Examples

      >>> from pandas.api.types import is_int64_dtype
      >>> is_int64_dtype(str)
      False
      >>> is_int64_dtype(np.int32)
      False
      >>> is_int64_dtype(np.int64)
      True
      >>> is_int64_dtype('int8')
      False
      >>> is_int64_dtype('Int8')
      False
      >>> is_int64_dtype(pd.Int64Dtype)
      True
      >>> is_int64_dtype(float)
      False
      >>> is_int64_dtype(np.uint64)  # unsigned
      False
      >>> is_int64_dtype(np.array(['a', 'b']))
      False
      >>> is_int64_dtype(np.array([1, 2], dtype=np.int64))
      True
      >>> is_int64_dtype(pd.Index([1, 2.]))  # float
      False
      >>> is_int64_dtype(np.array([1, 2], dtype=np.uint32))  # unsigned
      False
