I think I misread the question and saw "==" as "="
But, the answer I gave should still help: the byteorder is a property
of the data-type. There is no such thing as "a's" byteorder. Thus,
numpy.float32 (which is actually an array-scalar and not a true
data-type) is interepreted as a machine-byte-order IEEE floating-point
data-type with 32 bits. Thus, the result will depend on whether or not
a.dtype is machine-order or not.
