A small contribution and a big question (timer/keyboard)

[DrDarius]

Cyrille,

Thanks for the explanation. Now it all makes sense.

The error value depends on what you reference it to: the HP Prime readout, or the stopwatch readout. In the latter case, after six hours of continuous running, the error stabilizes on 2.4012... %.

If I may suggest, in the next f/w revision for HP prime you should add a small note that for the h/w rev. D (G2) the real time interval returned by TICKS() is not exactly 1ms, but there is 2.4% error. The TICKS() help note might be a good place for it. It's only one sentence, but it may save a lot of time of somebody who, like me, runs into this problem. (That said, I agree that it's not a typical problem, and there may be nobody else needing this info.)

Thanks again for clearing it up for me.

Darius
