I mean sure. Unlimited precision calculation I don't think is the proper domain of the cheap desk calculator.

I mean what do these do? I think like 10 digits worth?

If you're actually doing something requiring over 10 digits of accuracy and you can reliably hit that you probably have a $10 million lab...

So honestly what are we talking about here...If it's pure mathematics this is a bad tool for that as well.

oh of course. But I meant being able to select a result or equation from 10 minutes ago in the calculator history without re-typing it!

These cheap calculators certainly have history. I think it's even persistent.

Chips with megabytes of non-volatile storage can be had for under a dollar at scale these days.

The TI-84 EVO brags about having 3MB on their $160.00 device. Cool TI, don't strain yourself...
