[issue30930] Element wise multiplication issue

[Mark Dickinson]

Mark Dickinson added the comment:

This is really a question for a NumPy mailing list, not for the Python bug tracker.

But the answer is that you're doing computations using 32-bit integers, and those computations overflow, leading to the odd results you're seeing. It looks as though your Octave computation is performed using floats, hence the different results.

Closing here: this isn't a bug (not even a NumPy bug, I'm afraid), and it's unrelated to core Python.
