That might be because I'm not understanding you very well, but I was
thinking that:

cdef dtype descr = PyArray_DescrFromType(NPY_FLOAT64)

would give you the float64 dtype that I thought you wanted?  I'm
shooting from the hip here, in between nieces competing for the
computer and my attention.

See you,
