Very interesting! Thanks for sharing this.

Are there any other calculators besides the HP-22, HP-70 and HP-80 supporting this input method (perhaps even some featuring an EEX button as well)?

By your description I take it that this works for digits other than zero as well?

I can confirm that hp30b does not.

I wonder if it is possible to reverse from scientific notation back to "standard" notation. I suppose that in contability you need to know all the digits in a certain number, an approximation with two, three or four significant digits in scientific notation is not enough.
