RE: epoch Prime
(01-05-2018 11:26 PM)salvomic Wrote: Maybe. But first of all you generally should not calculate a mod b by means of b*fp(a/b). This causes roundoff errors. There is a mod command that handles this exactly. And then you do not have to calculate hours, minutes and seconds manually. Your method also works with fp(ep/86400) which again causes roundoff errors. I assume the Prime has a command that converts decimal hours to h.ms. I would code it this way (you'll have to translate this to PPL): yr = IP(da) mt = IP(100 * da) mod 100 dy = IP(10000 * da) mod 100 And the same way for the time given as hh.mmss: hours = (ep mod 86400)/3600 hhmmss = hms(hours) hh = IP(hhmmss) mm = IP(100 * hhmmss) mod 100 ss = IP(10000 * hhmmss) mod 100 BTW, does the Prime have a command for integer division? Like "DIV" or "\" in other programming languages? (01-05-2018 11:26 PM)salvomic Wrote: How to make an optional parameter to input (or not) the time zone in epoch()? This can be answered by the Prime experts. I only can say how this could be done in VBA where parameters can be declared "optional". ;-) (01-05-2018 11:26 PM)salvomic Wrote: Then I'll see to return for epoch2date both a "pretty formatted date" and a "calc date" as {2018.0105, 23,9721} for date and time.fractional... You may return time and date according to ISO 8601: 2018-01-06T10:29:35+01:00 Dieter |
