I'm totally in favor or having that page. In my gmail account almost every

Maybe one day I'll try to put them together.

There is np.result_type. It does the handling of scalars as normal,
dtypes will be handled like arrays (scalars are allowed to lose
precision).

Of course, I mean dtype of the array.

Is there a way to extract the size of array that would be created by
doing 1j*array?
The problem I'm having is in creating an empty array to fill with
complex values without knowing a priori what the input data type is.
For example, I have a real or int array `a`.
I want to create an array `b`
