We need information on history of calculators, early mechanical calculators, etc...
Please make comments about articles on the talk pages. :^) — Frecklefoot 19:08, 7 Oct 2003 (UTC)
This article is supposed to be about electronic calculators. There is another article for mechanical calculators, where earlier history should go. Gah4 ( talk) 18:59, 8 September 2016 (UTC)
Graphing calculator has been a re-direct to calculator for nearly a year. Can we start a discussion about whether graphing calculators are ready yet to have their own article?? 66.245.2.190 17:15, 6 Aug 2004 (UTC)
OK, to make this more interesting, as I understand it the SAT requires test takers to have a graphing calculator. Presumably some could survive with a non-graphing calculator, but rules are rules. The oldest on the list, last I looked, is the HP28C, which is a graphing calculator from about 1989. It does seem, then, that the graphing feature is more fundamental than I might have thought. Gah4 ( talk) 22:38, 8 January 2017 (UTC)
The article doesn't mention that TI submitted a patent for the handheld calculator in 1967, which they (as well as the Wikipedia article on TI) define as "inventing the handheld calculator". However it seems that the patent application didn't stop other companies from introducing handheld calculators. It seems that the handheld calculator introduced by Canon in 1970 was in partnership with TI. Someday someone who knows the correct story on this stuff should probably add a note about this.

Just read an article where the db800 by Digitron was described as the first European pocket calculator. Should it be mentioned in the History section? -- Killing time, till it retaliates. ( talk) 18:04, 19 June 2013 (UTC)
This article neglects to mention what people used for calculators before mechanical calculators. I know very little about this area, but it seems as if someone who did could add a section after abacus to talk about using human labour to produce calculations.
Especially of interest may be firing solutions in WWI/WWII-era submarine (I believe the person in charge of that was called a calculator, IANANO), and the scores of women that signed up to become calculators for the war effort.
Unfortunately, I know very little about this. Not even enough to make a heading with a stub. -- Eienmaru 13:23, 13 August 2005 (UTC)

This article should include how calculators actually work. I haven't been able to find out how they do anywhere on the internet. —Preceding unsigned comment added by 4.164.243.231 ( talk • contribs) 20:06, 1 October 2005
I strongly suggest we add a "How (pocket) calculators work" to the article. I found an interesting explanation here: http://www.madsci.org/posts/archives/2001-03/984867136.Cs.r.html Basically, it suggests that calculators convert operations (at least addition) into binary notation, do the calculation then convert it back to base 10. But what about trigonometric functions and square roots? How does a calculator know the answer there? It's clear logic gates are involved, but it would be interesting to see an explanation that makes sense. Would anyone know how to explain this in the article? I might if I find some more background info, but if someone understands it already then that might save time. Brisv e gas 12:47, 1 June 2007 (UTC)
This article is only about electronic calculators. It is not about all calculators. Why does it have the wrong title? Joja lozzo 02:11, 1 August 2011 (UTC)
Calculator → Electronic calculator — Calculator page has been split into mechanical calculator and electronic calculator but the Electronic calculator (redirect) is protected. Calculator should become a disambiguation page with links to the two halves of the split. I can do all the moves etc if someone would unprotect Electronic calculator.

Wikipedia's policy on article titles.Assuming we redirect Calculator to Electronic calculator, this discussion seems to center around balancing conciseness (and wp:COMMONNAME) against wp:PRECISION. (See WP:NAMINGCRITERIA.) I don't think "calculator" is a term that is going to mislead anyone, people aren't generally going to be surprised to see just electronic calculators described here. WP:PRECISION doesn't take such an absolutist view on things that this kind of heroic effort to avoid the slightest possibility of ambiguity is necessary; it even says: "If the topic of the article is the primary topic (or only topic) for a desired title, then the article can take that title without modification."

Wikipedia's policy on article titles.On such an important topic, and in which so many are so interested, shouldn't we have an overview article at calculator rather than a redirect?

My understanding of our naming guidelines is that this question here boils down to wp:COMMONNAME, and has little to do with PRIMARYTOPIC or PRECISION.

Note that the SAT now requires a graphing calculator. It looks like they won't even let you use a non-graphing, new or old, model. They specifically exclude models with an alphanumeric keypad, as that does make it easier to cheat. [1] The ACT is more restrictive, but still allows the more common calculators.

I worked on electronic calculators during the mid to late 1970's. This article, like most articles on electronic calculators I have seen leaves out a whole segment of calculator designs. The very early electronic calculator designs used 'counting tubes' and later counting circuits that mimicked the mechanical veeder root designs that had a series of counting wheels that went round and round generating a carry to the next wheel when the ten count was reached. The next most mentioned design was the application specific chip sets that immediately preceeded the actual microprocessor designs (the 4004 and 4040 intel chips and the PPS4 and PPS8 rockwell chipsets). However in between the counting tube and counting circuit designs and the first application specific chipsets there were quite a few machines that used many discreet i.c.'s that implemented a serial calculator design. The Frieden 130 and the Victor 500 series (that used crt displays) were actually of this type. The memory element was either a magnostrictive delay line of a shift register (either dynamic or static). The calculation circuits were actually single bit arraignments. Numbers were coded into a parallel to serial shift register (keyboard input) and then dumped into the serial memory. As the bits came out of the serial memory they went into another register just prior to going into the adder/subtracter. the data stream then went into one of three or four display registers (to be sent to the 'stroke generator' that drove the crt display). One of these registers (one could call it the 'accumulator) would be sent back to the serial memory. Most of my experiance was with the Victor line of calculators, but I also worked on Sharp, Casion, and a host of other serial based machines. There was usually a binary counter and decoder to develope timing signals to get the data into and out of the serial memory in a timely fashion (this was usually reffered to as a 'stste machine'). I have some info on the discreet chios that were used in these early designs and would love to collaborate with someone on expounding on this design. Technogeezer ( talk) 02:24, 2 April 2013 (UTC)

Are there any current basic desktop calculators using RPN? If not, is it possible to obtain an HP25 calculator? — Preceding unsigned comment added by 101.186.160.111 ( talk) 04:47, 18 December 2015 (UTC)
HP25 are available on eBay, but a little expensive. They are usually considered pocket calculators, but when I bought my HP25C for college, my dad suggested I buy the security cradle for it. That keeps it on the desk. Of the available older HP calculators, the 28C and 28S are often reasonably priced, and fun to use. Gah4 ( talk) 00:48, 26 August 2016 (UTC)
The article mentions the: "Cal-Tech" project, and has references that don't seem to reference the name. Is there anything that shows that name? I do remember some calculator chips, such as the CT5001, that were named Cal-Tex which I always thought was a combination of California and Texas, but might have been something else. More specifically, I am wondering if the name is at all related to Caltech. Gah4 ( talk) 20:45, 23 August 2016 (UTC)
I just tried to improve the article by adding the mention that there are calculators performing exactly the same functions as all the now historical electronic calculators and those comments were removed. It is relevant to an article titled "Calculator" that the same technology once available only on a hand-held device is now available on the web and on mobile devices and now a whole calculator can be built in minutes that uses any conceivable equation on a calculator button. This is very relevant to the evolution of the calculator and I'm not understanding why this was removed? — Preceding unsigned comment added by Michael Bartmess ( talk • contribs) 20:32, 18 March 2014 (UTC)
Bit serial logic designs are more common in calculators whereas bit parallel designs dominate general-purpose computers, because a bit serial design minimizes chip complexity, but takes many more clock cycles. As far as I know, it is usual, from pretty much the beginning of electronic hand calculators through today, to do BCD digit serial arithmetic. Even more, the wikilink links to serial communication, and not bit serial ALU discussion. The logic for a BCD digit serial add/subtract is fairly simple, and it is fed by, and feeds into, shift registers. The shift registers then recirculate in time with the display multiplexer to keep the display going. This also led to the Intel 4004 as a four bit processor, convenient for doing BCD arithmetic.

There is Disagreement over the use of calculators in school? A certain 8th grade student studying in Europe cannot do 25+10, in his head, but depends on his calculator to do it. Why is there disagreement? Calculators certainly suppress arithmetic skills in young students. Soon we shall see arithmetic blockheads around the world. And calculators are getting more smarter, but students are getting dumber. Today's students cannot use a 1 line scientific calculator from the 1990s. Polytope4D ( talk) 01:48, 14 January 2019 (UTC)

The article says BCD rather than a floating-point representation which doesn't make sense. Floating point or fixed point can be decimal, binary, or any other base. Gah4 ( talk) 04:13, 26 April 2021 (UTC)
The article says: Pocket-sized devices became available in the 1970s, especially after the Intel 4004, the first microprocessor, was developed by Intel.... Is this meant to suggest that the availability of the 4004 led to more pocket-sized devices? (As far as I remember, Busicom build desk calculators.) Gah4 ( talk) 19:57, 12 August 2022 (UTC)

Bit serial logic designs are more common in calculators whereas bit parallel designs dominate general-purpose computers, because a bit serial design minimizes chip complexity, but takes many more clock cycles. As far as I know, it is usual, from pretty much the beginning of electronic hand calculators through today, to do BCD digit serial arithmetic. Even more, the wikilink links to serial communication, and not bit serial ALU discussion. The logic for a BCD digit serial add/subtract is fairly simple, and it is fed by, and feeds into, shift registers. The shift registers then recirculate in time with the display multiplexer to keep the display going. This also led to the Intel 4004 as a four bit processor, convenient for doing BCD arithmetic.

There is Disagreement over the use of calculators in school? A certain 8th grade student studying in Europe cannot do 25+10, in his head, but depends on his calculator to do it. Why is there disagreement? Calculators certainly suppress arithmetic skills in young students. Soon we shall see arithmetic blockheads around the world. And calculators are getting more smarter, but students are getting dumber. Today's students cannot use a 1 line scientific calculator from the 1990s. Polytope4D ( talk) 01:48, 14 January 2019 (UTC)

The article says BCD rather than a floating-point representation which doesn't make sense. Floating point or fixed point can be decimal, binary, or any other base. Gah4 ( talk) 04:13, 26 April 2021 (UTC)
The article says: Pocket-sized devices became available in the 1970s, especially after the Intel 4004, the first microprocessor, was developed by Intel.... Is this meant to suggest that the availability of the 4004 led to more pocket-sized devices? (As far as I remember, Busicom build desk calculators.) Gah4 ( talk) 19:57, 12 August 2022 (UTC)
