# dask.array.Array.astype

Array.astype(dtype, **kwargs)

  Copy of the array, cast to a specified type.

  Parameters:
    dtype str or dtype

      Typecode or data-type to which the array is cast.

    casting{‘no’, ‘equiv’, ‘safe’, ‘same_kind’, ‘unsafe’}, optional

      Controls what kind of data casting may occur. Defaults to ‘unsafe’ for backwards compatibility.

      - ‘no’ means the data types should not be cast at all.

      - ‘equiv’ means only byte-order changes are allowed.

      - ‘safe’ means only casts which can preserve values are allowed.

      - ‘same_kind’ means only safe casts or casts within a kind,

          like float64 to float32, are allowed.

      - ‘unsafe’ means any data conversions may be done.

    copy bool, optional

      By default, astype always returns a newly allocated array. If this is set to False and the dtype requirement is satisfied, the input array is returned instead of a copy.

      Note

      Dask does not respect the contiguous memory layout of the array, and will ignore the `order` keyword argument. The default order is ‘C’ contiguous.
