DM15CC? THIS is a calculator for real men!  Joerg Woerner  02182012 Hi Guys, You are talking recently a lot about credit cardsized calculators. Are you kidding? This is America, the land of the Ford F150 Pickup Trucks. Are you driving the Smart car or the new Scion iQ? This is now a calculator for REAL men:
Have fun, happy calculator hunting and have a great weekend,
Joerg

Re: DM15CC? THIS is a calculator for real men!  Joerg Woerner  02182012 And the one above the [ON/OFF] key that it shouts back ;))

Re: DM15CC? THIS is a calculator for real men!  hpnut  02182012 yup, real RPN calcs have no = :)
Re: DM15CC? THIS is a calculator for real men!  Gerson W. Barbosa  02182012 Yes, real RPN calcs are nonpareil :) From http://www.merriamwebster.com/dictionary/nonpareil :
NONPAREIL: having no equal
Re: DM15CC? THIS is a calculator for real men!  Namir  02182012 How about a clear scan of your credit card??? Should help us get many units of the machine in the picture. :)

Re: Yes, it's all about my gold card  Katie Wasserman  02192012 Joerg, I've been meaning to ask you for the longest time..... What's so special to you about 2*SQRT(2) that you show this on so many of the calculators in your pictures? Not that there's anything wrong with this irrational number, but it would not be at the top of my list of exciting numbers I have known :) Katie
Re: Yes, it's all about my gold card  Joerg Woerner  02192012 Katie, Good question... I was inspired and mentored by Viktor T. Toth when I started the layout of the Datamath Calculator Museum and he used for all his calculator pictures pi = 3.14159265... in the display.
Long before (this was in 1999) I used already SQR (8) * 100000  282842 = ??? Now you know my little secret ;)) Good that you didn't asked why my eBay handle was "jogibogi" till a few years ago. That's something I would whisper in your ear;))
Cheers, Re: Please translate to RPN!!!  Joerg Woerner  02192012 Oops  can you translate the 282842 thing to RPN, please????
Regards, Re: Please translate to RPN!!!  Gerson W. Barbosa  02192012 Not related to your request, just an attempt to show SQRT(8) might be an interesting number :) 8 SQRT EEX 8 * 17 1/x y^{x} (RPN) Regards,
Gerson.
Re: Please translate to RPN!!!  Katie Wasserman  02192012 Only 6 significant digits, not a good enough reason for me to like this number :)
Re: Please translate to RPN!!!  Gerson W. Barbosa  02192012 Ok, sqrt(2) is better, and given infinite time it would help compute pi to the last digit :) http://www.golfscript.com/golfscript/examples.html I don't know GolfScript but I guess the 29byte script for 1000 digits of pi uses the Vieta's formula, like your 12step program for the HP12C:

Re: Yes, it's all about my gold card  Paul Dale  02192012 Quote: This fails for the 34S. The sixteenth digit is a zero.
Re: Please translate to RPN!!!  Gerson W. Barbosa  02192012 Quote: A more interesting result, perhaps: pi^34 = 8.00010471505*10^16 The underlined digits match exactly the first five significant digits of pi/3. This leads to the polynomial x^34  (1/3)*10^12*x  8*10^16 = 0 whose positive real root is 3.14159265364 Nice coincidence, isn't it? _{Edited to correct a mistake in the second coefficient}
On the HP 50g [ 1 0 0 0 0 0 0 0 0 returns a positive real root 3.14159265364. The wp 34s polynomial solver should return 3.141592653644187, but I haven't tested on it yet.

OT: Re: Please translate to RPN!!!  Katie Wasserman  02202012 Gerson, Golfscript has been mentioned here a few times, thanks for the reminder to looking into this some.... It looks to me like a mix of RPL and APL with a little LISP thrown in, only just for integers. I like all these characteristics in a programming language but not the "write only" usability of it. I wonder if there are more than 10 people in the world who've used this more than once. Do people here have experience with GolfScript? I see that Oliver mentioned building this into his ND1, but I'm not sure if that ever happened. Katie
