Augmented assignment modifies numpy arrays in-place, so the usual
casting rules for assignment into an array apply. Namely, the array
being assigned into keeps its dtype.
If you do not want in-place modification, do not use augmented assignment.

enigma that is made terrible by our own mad attempt to interpret it as
though it had an underlying truth."
