# numpy.ma.MaskType.newbyteorder

`MaskType.``newbyteorder`(new_order='S')

  Return a new `dtype` with a different byte order.

  Changes are also made in all fields and sub-arrays of the data type.

  The new_order code can be any from the following:

  - ‘S’ - swap dtype from current to opposite endian
  - {‘<’, ‘L’} - little endian
  - {‘>’, ‘B’} - big endian
  - {‘=’, ‘N’} - native order
  - {‘|’, ‘I’} - ignore (no change to byte order)

  Parameters: | new_order : str, optional Byte order to force; a value from the byte order specifications above. The default value (‘S’) results in swapping the current byte order. The code does a case-insensitive check on the first letter of new_order for the alternatives above. For example, any of ‘B’ or ‘b’ or ‘biggish’ are valid to specify big-endian.
  Returns: | new_dtype : dtype New `dtype` object with the given change to the byte order.
