RE: Let's vote for suggestions and bugs
One truly Wonderful feature still [ Missing ] from HP Prime is the Porting of Giac [ Longfloat ] / GNU [ MPFR ] Libraries, incorporating the ability for [ Arbitrary Precision ] Floating Point Arithmetic to HP Prime CAS [ Kernel ].
Its worth to mention that even HP 49/50g ( with all their hardware limitations ) have a third party [ Longfloat ] package ( available through HPCalc.org at [ http://www.hpcalc.org/details.php?id=5363 ] ). Also any Android [ Smartphone / Tablet ] with XCas/Giac App installed, do indeed have plenty access to Multiple Precision Floating Point capabilities, still [ Lacking ] from HP Prime ( although sharing similar ARM base CPU and hardware architectures ). The task of Porting Giac Longfloat / GNU MPFR Libraries to HP Prime would be more than compensated and worth the effort, since it would allow HP Prime to be the [ First ] handheld [ Calculator ] with Longfloat CAS support at its [ Kernel ] Level. Yours Sincerely, with Congratulations for the Superb idea of collecting all Suggestions and Bug Reports in Centralized Pages, allowing HP Staff to know HP Prime users most desirable and Wanted Features and Resources. My Best Wishes and a Very Nice and continued Work to All, Prof. Ricardo Duarte

RE: Let's vote for suggestions and bugs
Just to Note that " Add [ product ] function to Math Template key " has been finally [ Implemented ] on Kernel [ 8151 ].
Some of the [ Actual ] PDF [ Documentation ] still shows the [ previous ] Math Operations Template [ Picture ] on some pages of the Manuals and User Guides. In a Next Post I will present the Full [ List ] of Pages from the PDF Documentation needing to [ Update ] the Math Template [ Picture ]. Yours Sincerely, wishing a Nice Work to All !

RE: Let's vote for suggestions and bugs
Some [ Easy ] to Implement [ Menu ] entry additions still [ Missing ] are:
Include [ rsolve ] and [ seqsolve ] under CAS [ Solve ] Menu and App [ Sequence ] submenus Include [ ztrans ] and [ invztrans ] in [ Transforms ] Calculus submenu Create a Math [ Statistics ] ( New ) Menu entry with [ mean ] [ median ] [ quantile ] [ quartile1 ] [ quartile3 ] [ quartiles ] [ stddev ] [ stddevp ] [ variance ] And a ( New ) Math ( Statistics ) [ Regression ] submenu with [exponential_regression] [linear_regression] [logarithmic_regression] [logistic_regression] [polynomial_regression] [power_regression] Include [ pade ] [ arcLen ] [ residue ] [ implicit_diff ] [ function_diff ] on CAS [ Calculus ] menu Include [ matpow ] [ charpoly ] and [ ker ] in Math [ Matrix ] Advanced menu Include [ expand ] [ factor ] [ exact ] as Touchscreen [ Buttons ] after [ sto > ] and [ simplif ] in the absence of allowing for a [ Full ] user Customization of the 6 Lower Panel Buttons. My [ preferred ] Suggestion still [ unimplemented ] is " Save / Load History in CAS " by Onkel Otto, since this is one of the Great Differences from HP Prime to TI Nspire ( which allows Saving in Distinct Worsheet files the actual command History Environment ). Finally its interesting to point to a [ Desirable ] Feature which has [ Not ] been Fully ( and Correctly ) Implemented, which is the [ Compound ] Differentiation of Expressions within [ Multiple ] variables, by means of the [ Template ] slanted [d] operator symbol See for Example: " Add [ n'th ] order Derivatives to Math Template key " and [ BUG ] REPORT: Distinct [ diff ] and slanted [d] operators Results for [ More ] than 1 Variable at [ http://www.tricider.com/brainstorming/2eKfifdjarx ] Main Suggestion Page. Yours Sincerely, wishing a Nice Work to all, with the Hope of Continued Future New Improvements to HP Prime !

RE: Let's vote for suggestions and bugs
===================================================================================
[ BUG ] REPORT: Distinct [ diff ], slanted [d] and Math differentiation [ Template ] operators Results for Differentiation with respect to [ More ] than 1 Variable ===================================================================================  I will be providing a Detailed [ BUG ] REPORT ( already described at the http://www.tricider.com/brainstorming/2eKfifdjarx page ), which may have been still unnoticed at all ( due to the vast number of suggested items on that page ).  The general syntax for [ Differentiation ] operator both by [ diff ] command or the slanted [d] symbol ( available from catalog ) is: diff( expression, variable [, variable, [ ..., variable ] ] ] ) or slanted [d]( expression, variable [, variable, [ ..., variable ] ] ] ) The results provided by [ Both ] forms of Differentiation should be the [ Same ], which unfortunately does [ Not ] happen for [ More ] than [ One ] variable ( even with Rev 8151 of the Kernel ), with only [ diff ] command producing the [ Correct ] result. Take for example the Differentiation of x^2 * y^3 with respect to y and then to x by diff( x^2 * y^3, y, x ) which Correctly produces 6*x*y^2 while by taking the Same compound Derivative by means of the slanted [d] symbol ( invoked from the command catalog ) [d]( x^2 * y^3, y, x ) Wrongly produces 0 If the Compound derivative were taken by Parts, even so the slanted [d] operator produces the Wrong result 0 by following the below order of instructions First [d]( x^2 * y^3, y ) correctly produces 3*x^2*y^2 if one now invokes the slanted [d] operator on the Produced last answer Result with respect to x one Correctly arrives at [d]( 3*x^2*y^2, x ) resulting in 6*x*y^2 but if one applies a Chained slanted [d] operator, by means of [d]( [d]( x^2*y^3, y ), x ) one arrives at the Wrong result of 0 Its interesting to Note that the slanted [d] Differentiation operator symbol, available from the [ Catalog ] of functions, presents a Differentiation [ Template ] at command line, while invoked, by the same way as invoking the differentiation Operator by touching on the Math Operations Template. To make things a bit more Clear, from the Example provided, imagine one taking the following order of operations, by First invoking Math Operations Template, then selecting the slanted [d] operator and entering the x^2 * y^3 expression at the numerator, and y variable at the denominator, producing the intermediate Differentiation only with respect to y [d]( x^2 * y^3, y ) resulting in the Partial Result 3*x^2*y^2 if now one Invokes the Math Template again and selects the slanted [d] operator and uses the command [ History ], by means of the Upward motion ( of the four direction cursor ), and [ Selects ] the Previous entry [ Input ] [d]( x^2 * y^3, y ) and press [ Enter ] as the Numerator expression to be now differentiated with respect to x variable ( at the Denominator ), one ends up with the [ Compound ] differentiation input first by y and then by x [d]( [d]( x^2*y^3, y ), x ) which produces the Wrong result 0 If after invoking Math Template and selecting slanted [d] operator ( with respect to y variable ) instead of [ Selecting ] the Previous entry [ Input ] " [d]( x^2 * y^3, y ) " ( by means of the Upward cursor ) one [ Selects ] the previous entry [ Output ] " 3*x^2*y^2 " as the Numerator, and specifies the x variable at the Denominator, one Correctly arrives at [d]( 3*x^2*y^2, x ) producing the Right answer 6*x*y^2 Its also interesting to note that while filling the Differentiation [ Template ] one may specify [ Compound ] Derivatives, by simply providing the [ List ] of Variables, separated by [ , ] Comma, at the [ Denominator ] of the Template. So one may Select the slanted [d] operator from Math Template, and provide the desired expression like x^2 * y^3 at the Numerator and provide " y,x " as the Denominator Variables [ List ], which will effectively produce [d]( [d]( x^2*y^3, y ), x ) which unfortunately produces the [ Wrong ] result of 0 Other Examples of [ Compound ] Differentiation just for Reference ( and to complement the provided example ), allowing for a Better compreension of What may be Actually going [ Wrong ] with [ Compound ] Variable Differentiation with the slanted [d] operator on Kernel 8151 of HP Prime are [d]( [d]( [d]( x^n, x ), x ), x ) which produces the [ Right ] answer while [d]( x^n, x, x, x ) by providing the x,x,x [ List ] at the [ Denominator ] of the differentiation [ Template ] produces the [ Wrong ] answer n*x^(1+n) Its also interesting to note that diff( x^n, x, x, x ) or diff( x^n, x$3 ) produces the [ Right ] answer. Its Clear that Distinct [ Compound ] Differentiation [ options ] provided by HP Prime by means of the [ diff ] operator command and the slanted [d] operator symbol ( from catalog ) and the Math Operations Template should be [ REVISED ] since undesirable Wrong results are Produced by Compounding the slanted [d] operator. It seems that some sort of [ Distinct ] Operator [ Priority ] for the [ diff ] command and slanted [d] symbol may be causing such problems. Yours Sincerely, with my Best Wishes to All, Prof. Ricardo Duarte

List of implemented things was updated.
"Grad support" request was removed from tricider, since it is implemented by 2016.04.14 r10077 Please use tricider only for requests and not for release notes of the firmware or request on tricider system itself (I do not control tricider) My website: erwin.ried.cl

RE: Let's vote for suggestions and bugs
Funny how the most popular item is "fully integrate RPN" and the least popular item is "remove RPN".
I mean, I like RPN, it's interesting... But wow, you guys REALLY like it. Just saying.

It's "interesting" if it's something one has (relatively) recently been exposed to. But if you've depended on it all through college and your working life thereafter, it's something else entirely.

RE: Let's vote for suggestions and bugs
I just wanted to bounce this thread again and restate my desire for multiple equation solver like found on the 50g.
I believe this is the Hewlett Packard patent on that methodology: https://www.google.com/patents/US5175700

Edit protection for fomula's in sover app
When you have a set of formula's together you can save them in a separate app that is great.
Now when you open that app it is quite easy to destroy one or more of those formula's. And if you edit such formula by accident the saved formula's in the app are also destroyed. This is a 'saved' app so why not ask if you want to save the changes if you exit the app? Or get a popup question if you start editing a formula in a saved if you really want to change that formula?

RE: Let's vote for suggestions and bugs
Backlight timeout option
Although certainly not a bug, I would like more than anything would to be able to change the screen (not calculator) timeout. I believe it's set to 30s which, for me, is incredibly annoying. I have been spending a lot of time with my Prime and many times, I am looking at the screen thinking about what I am doing, or where I want to go with what I am working on. Then, the screen dims. If I select Esc, I lose the screen I'm on. If I touch the screen (for example), the point on the graph I have selected changes ... ahhhhh. Would it be difficult to add an option to modify the backlight timeout (similar to the TOFF auto off feature)? Jim

Until they make this usersettable, here are the two workarounds that I use. (1) When it dims, press Shift twice to brighten the screen without messing up anything you're doing. (2) Plug in a powered USB cable. It doesn't have to be connected to a computer; any USB power will prevent the screen from dimming. I use the supplied battery charger wall wart + USB cable.

RE: Let's vote for suggestions and bugs
The New public beta is definite improvement, indeed!
However, some things could also be put in the plate: • An Help system also for custom programs (CAS and HPPPL) to show in the Help; alphabetic order in Catalog > User • Anova 2 in Statistic 2 var • A Probability App with every the CAS already included (and maybe others) distributions, graphic... • Some advanced analysis commands in CAS, like Elliptic integrals (and Jacobi functions), Fresnel integrals, Bessel functions, Surface and Flux integrals... • QPI as standard command in Home and CAS. For some of them I put some ideas in the Prime Software Library, but it would be better to have them integrated in the FW and in a better way than I made Please, vote for those if you like :) Salvo ∫aL√0 (salvomic, IT9CLU), HP Prime, 50g, 12C, 15C :: HP Prime Software Lib
