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.

Hi, Joe!

9.99999999999 ->HMS is 9:59:59.999999964, exactly, and so the rounded 12-digit answer should be 10:00:00, which is what the 48G gets. Unless you meant that Pekis' formula should have returned either 10 or 9:59:59.9999999

Cheers, Werner
