Forgive me if I haven't understood your question, but can you use
PyArray_DescrFromType with e.g NPY_FLOAT64 ?
I'm pretty hopeless here. I don't know how to put all that together in
a function.
That might be because I'm not understanding you very well, but I was
thinking that:

Hi,
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

You're looking for PyArrayScalar_New and _ASSIGN.

Undocumented (bad), but AFAIK

I'm looking for the C-API equivalent of the np.float64 function,
something that I could use inline in a Cython function.
I don't know how to write the function. Anyone have one sitting
around? I'd like to use it, if it is faster than np.float64 (np.int32,
np.float32, ...) in the Bottleneck
Wouldn't that be a cast? You do casts in Cython with double(expression)
and that should be the equivalent of float64 I think.

Or even numpy.float64_t (expression) if you've cimported numpy
