Quiz-What was the 1st desktop calc with Transcendental functions?? - zeno - 09-17-2006 It was not the HP9100A....
Also, what month and year did it come out for public sale??
Re: Quiz-What was the 1st desktop calc with Transcendental functions?? - Steve S - 09-17-2006 I'm going to guess that it was the LOCI-1, issued by Wang Labs in the latter half of 1964...

The Wang LOCI-1 did not have both log functions and trig functions...I am referring to one that had log and Trig functions together.
Re: Quiz-What was the 1st desktop calc with Transcendental functions?? - Kalevipoeg - 09-18-2006 My guess is the soviet calculator EDVM

Nope, that came out 3 years after the first one.
Re: Quiz-What was the 1st desktop calc with Transcendental functions?? - Steve S - 09-18-2006 ...Not so fast there, Zeno! All you asked for was "transcendental functionS" (Cap "S" mine).
Since the LOCI-1 also did mutiplication and division by logs, I submit that it did, in fact, do transcendental functionS (...just not the ones we might usually think of...).
Re: Quiz-What was the 1st desktop calc with Transcendental functions?? - GE - 09-25-2006 Sooo, what was the expected answer to that question ? Re: Quiz-What was the 1st desktop calc with Transcendental functions?? - Eric Smith - 09-26-2006 Well, we give up. What's your answer?
Re: Quiz-What was the 1st desktop calc with Transcendental functions?? - Ken C - 09-26-2006 I did some programming on the Wang 500 series in 1971 specifically for the trancendential functions including trig and log. I seem to recall that most of the functions iterated only to 6 places and we needed at least 9. The little hp35 had the functions with enough precision, but was not programmable.
Re: Quiz-What was the 1st desktop calc with Transcendental functions?? - Katie Wasserman - 09-26-2006 Hmm... I've got a Wang 520 sitting here and it seems to be at least as accurate as the HP-35 for log and trig functions. It computes everything to 10 digits and compares quite well with the 32SII. (However, I have to admit that the inverse trig functions on this particular machine don't work -- there's a broken ROM wire in there somewhere.) It's my favorite (non-HP) calculator!
Re: Quiz-What was the 1st desktop calc with Transcendental functions?? - Ken C - 09-27-2006 Problem was not in the number of digits displayed but the actual accuracy in generating the trans functions. I just don't remember how the Wang stacked up. Re: Quiz-What was the 1st desktop calc with Transcendental functions?? - Paul Dale - 09-27-2006 Babbage's difference engine?
Re: Quiz-What was the 1st desktop calc with Transcendental functions?? - Kalevipoeg - 09-28-2006 or "Mirifici Logarithmorum canonis descriptio" by John Napier, 1614 ?
