No, it's still not answering my question why current calculator (HP Prime) with 32bit ARM9 CPU @400MHz has +/- the same number of significant digits as calculator 40 years old (TI-58/59) with 4bit TMC0501 @200kHz. Maybe my question is badly formulated? Nevertheless thank you for your time you put into your reply.

This explains why the results of the HP Prime in Home mode are the same as the HP 48. Thank you, Didier, now I got it. Prime G2, 15C CE |
