No, in Numeric the arrays are always assumed to be in machine byte order 
and so sys.byteorder tells all (Numeric.LittleEndian is a Boolean that 
is also defined).

In scipy core, arr.flags.swapped tells you if the bytes are in swapped 

Then,  sys.byteorder or scipy.LittleEndian indicates the machine order.

Or you use the array_interface descriptor.

is_big_endian = (arr.dtypestr[0]  == '>')
