Do you still use stand-alone ("pocket") calculators?

With so many different kinds of calculators, surely you end up preferring just one? I can't learn/rememberr how to use half the functions of one calculator. Then there's the adjusting to the various layouts/fonts/color schemes of the buttons.

If I collected calculators, I'd have 6 of the same one. :)

And for me, it'd be the one on the second column, second row. That fx-115MS. That's my workhorse. I still see it for sale, but the price is going up. Maybe I should buy a few.

You are so correct, I have many calculators that I have gained over the years, because it seemed that each one had a unique function / feature that I thought would be handy to have, and when the time comes to use it, I can't remember how to do it.

The HP prime is my primary calculator.

And this is why I dropped my 50g in favor of a 48G+. I couldn't keep up with battery usage. On the other hand, my 48G+ has been on the same set of non-alkaline batteries for almost a year now.

My HP 48G+ finished it, took a long time (sorry, didn't measure it), but it arrived to a result of 717.928325369.

My HP35S failed to compute due to the discontinuity, but the 48G emulated on my Galaxy S8 (Droid48) finished in about 45s with the same result of 717.928325369.  :-+
