That is quite nice!  Is the display cover glass or plastic?

I think the "most precise pocket calculator" is the WP-34S.

It uses DecNumber library with up to 50 decimal places precision.

Just so you know, YouTube has this video marked as "unlisted".  I'm not sure what this means, but I don't see it on my YouTube account subscription page.

darik:
To show the full precision, use shift-decimal (SHOW).
