• HP calculators: origin of prefix key labels f and g

  I wonder about the motivation of the developers of HP to label the keys to prefix of RPN calculators in the 1970s and 80 by the letters f and g. obviously, the reason was not absolutely background as angles arrows were later invented instead. Compare: hp15c.org and Wikipedia/HP - 32S

  Hello

  I see you have some answers on MoHPC. I'll reference the thread here for someone down on this post.

  Having a problem of function with a new premium calculator, s/n [number of Series edited by Moderator].

  X to Y (X ^ Y) ensures actually Y to X power.

  Example: 2, entry, entry 6, X ^ Y, not return 64, 36 as it should.

  Is there any fixes for this?

  Thank you

  Hello

  The function is:

  "First argument" to the "second" power

  where X is 'First argument' and there is 'second argument.

  You have entered 2 and 6, so 2 ^ 6 which is 64.

  That's how work calculators 28 c/28/48 / 48G / 49G / 50G.

  There is no concept of X and recorded, as was the convention on battery level RPN calculators 4.

  On the 28 28 c/s the power button was simply designated as ^, on the 48 series, it was changed to Y ^ X but probably only because of the legacy application.

  the X ^ was used on some algebraic calculators (for example HP38g / 39g / 40g). The first is essentially an algebraic calculator (out now on line 38G / 40G) and mode RPN was probably introduced only for legacy demand (no RPN/RPL programming).

• Application of emulators calculator hp classic for WebOS

  Never is better made than the hp1x line calculators.  My favorite was the hp11c, which I've owned for nearly 30 years and which serves me well today.  Long abandoned by hp, they still regularly sell on ebay for more than $200 (twice the original price, not to mention inflation!).  But now we are in a new era and RPN calculators are hard to find.

  Recognizing their popularity and eventually bowing to the fact 3 Parties provided simulators/emulators of these wonderful devices, Hewlett Packard has started selling emulators for several models for iPhone.  (see http://www.macworld.com/article/141364/2009/06/hpcalcapps.html)  Now that HP owns Palm, it would be really wonderful if they would bring this range of products for WebOS.  PLEASE, I BEG YOU!   And it would be even better if they understood a hp11c emulator in the offerings.

  Thank you.

  Palm has a website for webOS RFE:

• HP - 50g RPN - how to increase the size of the variable icon in the command screen in the RPN

  Greetings.

  How can I increase the size of the icons 'F' keys for variables in the RPN command line window?

  My reason for this is to be able to see the full name of the variable.

  Thank you.

  Edit: Perhaps sizes of keys to function 'F' is what determines the size of the variable icon. Does this mean that it cannot be increased?

  If you press SHIFT RIGHT and then press the ARROW KEY down, you can see more than 5 characters that are currently displayed for the softkey text.

  a second solution to think abou... to help the CSE function and custom designed GROBs.

  (However, take into account the current size of the police... how small it really is possible and stay legible-

  You must take account of the resolution of the screen of 50 G... it's not a 'Tablet' hi-res-like display)

  See the example on page 20-4 of the 50G users guide.

  a copy of the user guide can be downloaded here:

• Programs written for earlier versions of graphical calculators HP can run on the HP 50 g?

  Hello

  I've seen many programs on hpcalc.org which are written for the HP 49, but I want to know if they work on the HP 50g as well. Also, will be programs written for earlier versions of the HP calculators work?

  ~ Zekelegge ~.

  Hi!, zekelegge:

  All programs written for the HP49G run OK, in the series HP49G + / HP50G, but not in HP48S/G/G + / GX series. Remember what HP49G + / HP50G emule Saturn microprocessor, 4 Mhz.

• Use infinite-sign of limits with RPN

  Hey people

  I have a small problem with the help of the infinity sign in the context of "limits" lim() in RPN Mode.

  I want to solve this example:

  2: 1 / x ^ 2'

  1: "x infinite = '"

  But unfortunately it is not accept it with reason 'incorrect syntax '.

  exact is set

  digital mode (Pavilion 3) I tried together and undefined

  Radian is set

  When I use 9.9999999E499 instead of the infinite sign without exact mode Ant it works, but is not very practical.

  PS. I have this example of (German), book of-the-art, but there is nothing written on special things for RPN Mode.

  Do anyone have a solution? Thank you very much and best wishes,

  Berni

  by reference to the users the Advanced...

  digital mode (Pavilion 3) should NOT be set

  EXACT mode

  by the following on the stack:

  

  4 left shift (calc)

  F2 (LIMIT button)

  F2 (key lim)

  result: 0

  OR, using the equation editor:

  

  EVAL

• First HP and RPN function problems

  I am filling a whilest the RPN setting function is active.
  
  Why do I receive the "Error: Syntax Error" when you paste a function?
  
  Does not allow the first HP for this or is there something I'm missing here?
  
  Should I really have to change the settings for RPN, algebraic or manual for an input function?

  Hello

  Use the ' ' when entering equations into RPN mode (mode RPN equations are algebraic expressions that need to be in ' ' brands)

• I found flaws in all of the calendars and the scientific calculators of Apple products. How can I send you my report pages 20 as a matter of course. Who should I go. This is a real case, and I am willing to work with Apple on this issue.

  Dear Sir/Madam,

  Topic: Default in some Apple products (important issue).

  This is not an unsolicited idea or suggestion (Please read)

  First of all, allow me to introduce myself as a teacher of mathematics, with more than 20 years of experience in the teaching of mathematics in Jordan.

  I take the liberty to write to you on a very delicate issue regarding the above topic. I'll try to be direct and fertilizers to point.

  Eight months ago, I have established contacts with the customer at Apple and succeeded to in explaining my intention to work with Apple on the flaws I found in all the following Apple products:

  -Scientific calculators built into the Apple iPhones and other products like Mack book pro (13 keys/operators applying bad mathematical concepts).

  -Calendars integrated into Apple iPhones and iPads (after a certain date).

  -Most of the calculators downloaded on Apple iPads (application).

  With my main concern during the final user, I already have reports submitted to Apple on the six keys with solid evidence and evidence supported with excerpts from various reliable resources that are no doubt as to the failure of these keys. I also presented copies of the date on which the calendar goes off track.

  Now iPhones for new generation of Apple (6s and 6 s-Plus) have already been launched on the market, keeping the same flaws, I decided to start contacts with Apple once again, hoping to succeed in reaching the right people at Apple to continue my rage in finding that the right to address this issue. I hope that you will respond positively.

  My worries and concern are oriented towards the end user and, in particular, students who take the responses of these calculators for granted when they are wrong and they don't realize.

  I have prepared a 20 page report although detailed on these defects and how to correct function solid evedence of reliable math textbooks. I'm ready to send this report to the person/department concerned, on which they can check and verify my claim with any or all of the following:

  ·       Apple/mathematicians engineers.

  ·       The mathematics books that are published by well known/good reputation

  publishers.

  ·        Calculators Casio or TI as the most reliable calculators in the world.

  ·        Reliable sources of mathematics of the internet.

  ·        Presentations power point math on YouTube.

  .        Math teachers well known working in renowned universities

  ·        American Mathematical Society.

  I reiterate my willingness to cooperate on the question above so that the genetions coming Apple products will be free by all means!

  I look forward to your positive reply,

  Sincerely,

  Nael

  This is a user to user forum.  Your message must be addressed to the Apple company.  Maybe a letter to Cupertino, California, is in order.  Your letter will receive no valid response here about your concerns.

• HP graphic calculator first: first RPN - battery display of items not in compliance with the User Guide

  In the HP User Guide first, in the section on page 48 RPN, the image shows the battery watch algebraic views of right which was calculated on the left side of the line battery, with responses on the side of each line in the stack.  When I do the same calculations, I only get responses from the right side.

  Is there a parameter that represents the lines of battery as in the user's Guide?  I can't find it if it's there.

  Thank you

  Nick

  The guide I think you are referring is the guide of July 2013.  These pictures no longer exist in new versions of the user guide.

  I haven't met a setting that causes the behavior used in these pictures.

• First crash of HP program running with arguments in the RPN

  (The first HP 20150427 firmware version)

  The following basic program will result in the application crash and HP first reboot when running in RPN mode. When executing, it calls for the parameters and then crashes when you press OK to continue execution of the program.

  If I switch to the entry of MANUAL it works very well, however I used to be a fan of RPN so by default, I'm in RPN mode.

  If I put two arguments on the stack and calls the program with CRASH (2) popping the arguments, it works very well.

  EXPORT CRASH (T, P)

  BEGIN

  PRINT (T);

  PRINT (P);

  END;

  Investigation on a bit further, the following program always works, regardless of the input mode:

  EXPORT WORKS()

  BEGIN

  T LOCAL, P;

  INPUT (T);

  INPUT (P);

  PRINT (T);

  PRINT (P);

  END;

  The problem is therefore a very bad error handling in running HP PPL, in the case of a stack overflow. In my view, that it is a BUG in the firmware; rather than crashing and restarting the first HP, it goes down gracefully with a "stack overflow" error

  How can I create an official bug for this problem report?

  This issue seems to be fixed in version 2015 6 17 (8151). I can't reproduce the error.

• HP - 50g written problem complex number. How to write (3 + i * 3 * sqr (3)) to RPN? (3, i3sqr (3))

  Hello everyone, I don't know how to write (i 3, * (3 * sqr (3))) RPN mode.

  Can someone help me please? I already searched the gug pdf guide help, without result.

  Thank you.

  Hello

  A few notes in the representation of a complex number as a vector:

  (1) the i is omitted, the second number is supposed to be the imaginary part.

  (2) the 50 g accepts only decimal numbers for vector representation

  Thus, at the entrance there. I guess you have the calculator in complex mode and exact mode (about not checked in "MODE"-> "SAE"), i.e. "C =" displayed at the top of the screen.

  RPN mode:

  Press 3 then ENTRY (3 is at level 1)

  Press ENTER again (3 is now duplicated and on both levels 1 and 2 - one advantage of RPN)

  Press ENTER again (3 is now duplicated and on levels 1, 2 and 3)

  Press the button of sqrt (x). Level 1 shows a 3 with a sign of the square root.

  Press on multiply key, level 1 shows 3· SQRT (3)

  Press LeftShift (white), then I (above the TOOL key), level 1 indicates an i

  Press on multiply key, level 1 shows 3· SQRT (3)· I have

  Press + key, level 1 shows 3 + 3· SQRT (3)· I have (or 3· SQRT (3)· i + 3 according to the parameter Flag - 27)

  If you want to keep the symbolic result (with the symbol of the 'SQUARE root'), leave it in this form, if you want to convert to vector format press (red) RightShift, then -> NUM (above the ENTER key).

  The result will be a decimal vector shape (3, 5.19615242271).

  Kind regards

• First HP - RPN Mode - enter an algebraic Expression

  First HP Calculator into RPN mode, is there a way to enter an algebraic expression?  For example, on HP 50 G, you use the check mark button, ' ' ' to start the expression, then continue as algebraic.  Should I just go to the CAs to do this?

  Enter the algebraic expressions on the first HP is done in the same way as on the HP 50 g: just put the tick marks around the expression.  On the first HP, the tick mark is a shifted key: [Shift] [()].

  Hope that helps!
