Bought it and sold it 2 months later. If it's RPN you're after, this is NOT the calculator you want.

Has the compass been evacuated?

I'll stick with the normal way.

My FX 880BTG got 😢😢 a totall of 51.6 seconds painfully to give the result 5.96393809 x10⁹¹

Make a 10 years later review of your calculator

Curious about the foundation and frost wall. It appears that the walls were set at ground level. Doesn't the wall need to go below the front line which is typically 2 feet or more?

Little late to the party, but the ti-30X pro can do the integration in 8 seconds.....which is shocking as the ti-36x pro is much much slower and basically the same model calculator

The fx-CG50 is faster than this thing.

Horrible as always. TI-36 ( . . ) wtf ? 15:14 RPN efficiency 2 pi NOT 2 <enter> pi . Automatic stack lift ? 18:14 again, he is not learning.

The unix dc program is an RPN calculator with arbitrary precision and an unlimited stack. It also has up to 256 registers and is turing complete. I should know, I went fucking insane with it and wrote a working base 64 encoder and decoder in dc as a weekend project some time ago. (dc's I/O makes this impossible by itself, so it had to be supplemented with a minimalistic C program that transforms its stdin into a list of numbers, dc is still doing all the logic work and is still turing complete, as I/O is not a requirement for turing completeness). Here's how your example could be expressed as a function in dc: 3.14159265358 sP # setting a pi constant in the P register 12k # setting the scale for 12 digits of decimal precision [SI 2 lP 2^*lI-5 11v+/ 13 2.5/7*+ LId!=d]sf # a macro implementing the example but replacing 17 with whatever was on top of stack before the macro was called 17 lfxp 36.729365442244 22 lfxp 36.128160010229 the lfx is where the macro is being executed. It loads the f register (lf) onto the top of the stack, which is a big string, and then executes it (x) as a string of dc commands (a macro) dc also reads a config file (written in dc) upon startup, so you can define frequently used constants and functions in that file and have it always available upon starting dc. The commandline on the GNU implementation of dc also uses GNU readline, so you can just press up to recall entire lines of input. Though I prefer to just write my stuff in a text editor and paste it into dc, or run it in dc as a file. Another cool thing you can do with dc is integrate it into vim. Since the vim text editor can just call external programs to process text in its buffer, and dc is happy to receive entire programs through stdin, you can just inline entire dc programs into your text file and then execute them by highlighting the lines in visual mode and running :!dc. Vim has its own built in ways of doing arithmetic (in insert mode: ctrl-r, =, followed by a math expression), but dc absolutely blows that out of the water It was written in B in 1969, before the first C compiler or even assembler was written for unix. While we're here, lemme show you a dc function I wrote to print a number with thousand separators [d(n) - print n with thousands separators doesn't assume stack starts with one item (T register) doesn't print unnecessary padding or comma (lI0<7, LTlI-1<6) ]c [ 1ST 0SI [0LTZ+LIZ+L0Z+L1Z+L2Z+L3Z+L4Z+L5Z+L6Z+L7Z+d!=d]S0 [d999<2]S1 [1000~r lT1+sT l1x]S2 [lI lT>4]S3 [lI0<7 n lTlI-1<6 lI1+sI l3x]S4 [0n]S5 [[,]n]S6 [[d100>5]x [d10>5]x]S7 l1x l3x AP l0x ]sd For those with a bit of assembly or systems programming knowledge, you might recognize this S0/l0x pattern as looking a lot like a stack frame, and you might appreciate that macros can consume items from the stack as arguments and return values by leaving them on top of the stack, a calling convention that makes them behave like a function. Most dc commands are single characters, the only exceptions are register load/saves, which take up 2, conditionals, which take up 2-3 (!=d, which runs the d register's contents as a macro if the top two of stack are not equal, is an example), and strings [...] which are variable length. So yeah the 0 macro is a cleanup macro that takes advantage of several things. The Lx command loads destructively from register x, popping off the top value on that register's stack (as opposed to lx, which just copies it), the Z command takes ToS and transforms it into a number (0 if it's a number, the length if it's a string), you can probably guess by now that the first part accumulates a sum while destroying all the registers it used, and if you recall the !=x command I explained a paragraph ago, combined with the knowledge that d duplicates ToS, you can guess that it takes that sum, consumes it, and does nothing with it since a number can't be inequal to itself. The function's actual execution begins at the line `l1x l3x AP`, where it calls the loop macros it set up earlier and then prints a newline. The loops break the number (which again is arbitrary precision, it can be infinitely long if you've got enough memory) down into groups, and then prints those groups out with zero-padding and commas as needed. The function takes care not to pad the first group, write a comma after the final group, or assume that just because something is on the stack, it is a group. Here's that macro again without any unnecessary whitespace: [1ST0SI[0LTZ+LIZ+L0Z+L1Z+L2Z+L3Z+L4Z+L5Z+L6Z+L7Z+d!=d]S0[d999<2]S1[1000~rlT1+sTl1x]S2[lIlT>4]S3[lI0<7nlTlI-1<6lI1+sIl3x]S4[0n]S5[[,]n]S6[[d100>5]x[d10>5]x]S7l1xl3xAPl0x]sd This is a calculator language :)

How much is the price of HP now

I collect scientific calculators. It took 2:52 for my hp 48sx. Just ordered me a 50g off ebay. I love hp calculators. They might not be the fastest (except for the prime g2 , witch I also own). The prime g2 smokes all the calculators. I just love rpn. And I already know how to program them. Go team hp! I am such a nerd. Lol

where did u find about the time computimg

11 years old but fun to watch. found out that ti84 plus can solve sum calcs that modern calculators dont

Was this late Spring perhaps?

Thank you!

thanks! great video

Hello! Thx for the video. With your experience, how are the prices compared with other supermarkets? I dont see to much people buying. You know something about their advantages or amenities? Thx a lot

Wow. What a beautiful place. I envy the young people taking romantic walks. That is, if they are smart enough to take it all in. Getting goosebumps now.

i have the TI-89 Titanium and HP 50G, i got the same times for the TI, the HP 50G is just a little over 4 seconds!..

They are dying as the modern phone does more, hense no one is making new calculators

Having run the calculation already under the Casio machines, wouldn't the cache of the CPUs have been primed, helping them perform faster?

re 1st calc: for complicated fractions cant you just hit the fraction bar first and it expands the fraction bar in a natural way?

wow, I have _never_ seen a presenter talk SO much _about_ the product rather than what the product does. it is an amazing, and annoying, trait. I'm moving on to other sites

How are your exponents of a smaller size font than the base number ? I have always wanted this. My exponents are the same size as the base number, which of course looks stupid and takes up too much space on the screen.

Thanks again ! Using to your explanations in part 1 I was able to key the example on my 12c (no pi or square key) : I stored a 7 decimals pi approximation in m0 and I used the automatic stack to get pi squared ; RCL 0 ENTER x. "RCL 0" copies pi value in register x. "ENTER" shifts the stack x->y->z->t, "x" key multiplies x*y both containing pi => pi squared.

Thanks a lot for this excellent RPN tutorial !

I tested on my Casio fx-991 CW and it took 51 seconds.

My hp-prime doesn’t have the function key under Menu in Plot mode but that functionality is available through the Trace submenus. I can however pinch open plots to zoom in. RPN is available in Home Settings>Entry

I had a TI-85 in high school, then a TI-89 my senior year. I gave up my graphing calculator in college and just used a simple basic $10 scientific calculator (Casio FX-260 Solar). I realized I was using my graphing calculator as a crutch, and was better off without it (I majored in Electrical Engineering, by the way). These things are such a rip-off. Use free tools like octave, python, wxMaxima, Google Sheets, or the expensive ones (Mathematica, MathCAD, Matlab, Excel) and develop some marketable skills instead of wasting your time on these overpriced toys. Or, get a free calculator app or rom and an emulator on your smart phone if you feel like you must have some kind of graphing calculator on your person at all times.

Ingles claims to have the lowest price. Don't believe that whopper of a lie. Walmart, IGA, and Food Lion are way cheaper than Ingles claims and I have the receipts for proof. I attempted to purchase a few things today with no success and I will NEVER be back. Staff was busy doing nothing but socializing with each other in the Deli and meat departments, no chance for getting any assistance, long lines and rude crowds. I watched a young man walk out the door with his basket without paying for any of it. No manager in sight and none of the other employees were doing anything about it and showed no concern at all.

The misaligned windows trigger my OCD 😅😅

The Casio is by far & away the best of these. Not even close...

which calc does,,,, if i draw graph,,, the calc finds its equation

Really good.

Great video, I like to watch these to keep me sharp. I am a retired engineer and started college in late 1970's and was using a TI SR51 II. Then a friend showed me his HP 25 and I was sold. I switched to a HP21 and that was it. Then from there went down the road, 41's, 31, 32, 33, 34C, 48 and now I am back to the 21. I found a like new used 21 on eBay. Also have three 35s, a 20 and a 32 around here My fear is I won't be able to get any HP RPN's down the road so I collect them.

amazing how cheap scientific calc have gone a long way! Nothing beats the traditional black color of the sharp! all calculators should be black color ;)

using a calculator should be as intuitive as getting into a new car!

HP 50G is the BEST!

If TI wants you to spend so much on the CX II, don't you think they ought to know what CX stands for in the first place, especially if they care so much. Nobody in Dallas could tell me. Do you or any of your viewers know?

Any chance you might be bringing those calculator videos back? Love to watch those!

1702 looks great in its wonderful new scheme, reminds of S&A 750.

Considering the popularity of the ASMR stuff a few years ago, I'm surprised more people aren't listening to these. It kinda proves people weren't there for the sounds. Thank you for making and sharing your recordings.

Very nice there Martin.

Hp remove it from website

Very good demonstration.

💯💯💯

Seems the dead cat works well, at least drops the wind noise a lot, and the view is definitely spectacular there, along with the stealth van.

Thank you Martin, quite enjoyed this one.
