What about Ivet Galabova (HiGHS)?

Definitely! Here there is no cancellation. I meant that the complex step, compared to other finite difference methods, doesn't produce cancellation (and is second-order).

That shit is amazing :) However, a single evaluation at x + i*h is required, you shouldn't subtract f(x) there. It avoids catastrophic cancellation.
