Re: HP or Texas? The difficult decision. - Garth Wilson - 07-28-2009 This does not appear to have anything at all to do with calculators. Is this spam??
Re: HP or Texas? The difficult decision. - Paul Dale - 07-28-2009 Download the link and you get a document about calculators. There is a 30 second delay to encourage subscription but after that it is good.

Re: HP or Texas? The difficult decision. - Garth Wilson - 07-28-2009 Unlike the first time, the page now says it has reached its 10-download limit, and I can't download it. I did get it just before I posted above however, and there was nothing on it about calculators.
Re: HP or Texas? The difficult decision. - Thomas Radtke - 07-29-2009 I don't bother downloading a PDF if there's no other content in your message except that link. But I'll answer the message title: The dicision is difficult only if you don't know what you want. The features offered by HP and TI calculators are not secret, manuals and additional information are available online.
Re: HP or Texas? The difficult decision. - Marcus von Cube, Germany - 07-29-2009 Saile, can you upload the file again. Its no longer available. Or can someone who has already downloaded the file put it somewhere else? (e.g. MegaUpload.com, where I have an account). I'll be happy to host it on my site if I can get it.
Re: HP or Texas? The difficult decision. - Marcus von Cube, Germany - 07-29-2009 I've uploaded the document to my site:

Re: HP or Texas? The difficult decision. - Arnaud Amiel - 07-29-2009 Thanks, just read the last paragraph and the conclusion is that the TI is more accurate and the hp easier to use...

Funny, I would think it would be just the opposite.
Re: HP or Texas? summary - marais - 07-29-2009 If you want an executive summary of the article, here you go: - HP's build quality is superior to TI's
- HP's documentation for the 25 was quite good, the 33's user guide - RPN is superior compared to AOL - RPN programs are shorter: 1 line of RPN equals 1.5 to 2 with AOL - TI internal precision is 11 decimals, HP seems to be only 8. TI wins in this (quite important) category.

Re: HP or Texas? summary - Gerson W. Barbosa - 07-29-2009 Quote: Nice article, but perhaps the author did not put the calculators to the right tests. What calculators would perform better in Savage Benchmark, for instance? http://www.hpmuseum.org/cgi-sys/cgiwrap/hpmuseum/archv016.cgi?read=103356 Regards, Gerson. ----- HP calculators don't perform well in repetitive tests, like squaring 1.0000001 27 times (see link below - results in the first column, %errors in the next one) because the results are rounded to the number of digits in the display (internally the computations are carried out to 2 or 3 more guarding digits though).

Re: HP or Texas? The difficult decision. - Garth Wilson - 07-29-2009 Thanks Marcus. I can finally see it. What I saw in my first download effort which I mentioned above was unrelated. French is my third language and I can't read it nearly as fast as English, but I'm anxious to get to it when I can give it the time.
Re: HP or Texas? The difficult decision. - hecube - 07-29-2009 Oh boy... I remember that issue of Science & Vie and I remember reading that article when IT CAME OUT!
I'm old...
Re: HP or Texas? The difficult decision. - Philippe Lasnier - 07-30-2009 Gosh. Science & Vie No 748 Jan/1980... I may even *have* it ;-)
