Show us the experiment, then.

That's what I timed too.

Actually, I thought that Octave had this conversion too. At any rate,
it doesn't affect the execution speed at all to use double i instead;
I just tried it too.

I can't think of any artifacts that could have taken place here. There
is no construction, memory management, whatever. Nothing of the sort.

Just show us the fucking code. And I mean this in a good,
non-confrontational way, and I hope you'll pardon my intensifier. :-)
