Original article in Advanced Pocket Calculators

Thank you very much, especially for the "Advanced Pocket Calculators" version. I read the HP journal version of this article many years ago, but it does not answer the question regarding the accuracy of the 13-digit internal functions of the HP-41, -67 or any other calculator. What the article essentially says is that 13 digits (HP-91 and newer) allow (nearly) correct 10-digit results, which had errors before when no guard digits were used. Or simply "13 digits give better results than 10 digits". Which nobody will deny. ;-)
