If you input 9.99999999999 (12 digits total) into any 12-digit HP, and run Pekis' HMS formula, you get exactly 9:59:60 as the result. Should be 9:59:59.9999999 of course.

The way I see it is that it is more of an "error" of the calculator limited precision. If the calculator had a higher precision, it would certainly return the correct answer with the right amount of 9's trailing at the end of it.
