Calculators - The Need for Speed

[@cerosietebpositivo351]

Nice vid! On the Prime you can use the command "time(whatever)" and it will return the time in seconds to perform any calculation. i.e: time(factor(x^100-1)) It will depends also if you have "complex" checked or not on CAS mode.

[@scottcollins7513]

Had no idea it could do that. Good to know. Thanks for the comment.

[@cret859]

Ah! Ah! From my point of view, all these five calculators give an instant result. My old and reliable HP-15C need more than 8 minutes to give me this result at full precision (FIX 9 format). If I am in a hurry, I can get an approximation in less than a minute, but only three decimals are trustfully compute.

[@scottcollins7513]

I appreciate the humor -- that all of these are relatively instantaneous when compared with the HP-15C.

quand cette calculatrice brillait dans les classes, j'avais encore des cheveux et ne savais pas encore ce qu'était un ordinateur. 8 minutes, bigre ! bonne journée C.Ret ;)

[@gerardzi7930]

There are a lot of CAS and it is difficult to compare performance on only one example on different hardware. The difference between thé calculator today 2022 is the performance of the CAS and thé possibility of setting it. This IS an important point revealed by this excellent video. Thanks

[@scottcollins7513]

Thank you, Gerard. Obviously, a single example is not very scientific, but it does definitely point out how vastly different the performance can be between similarly-priced calculators (not including the hp Prime). Thank you for leaving a comment.

[@irishchocolate3872]

Speed is important but not everything. The Casio ClassWiz and the TI-36XPRO are still the 2 best non-graphing calculators. This is because they are the only 2 that will let you “Solve within solve.” What I mean is on either of these machines you can still access the integration function or the differentiation function in the linear solver. The Casio 115ES Plus won’t let you do this. Even some graphing calculators won’t let you do this. This is the one capability that makes the Casio ClassWiz and TI-36PRO unbeatable as far as advanced applications are concerned.

[@scottcollins7513]

This is an interesting point I have never explored, but I can see where you might want to use the calculator to, for example, determine what upper bound of a definite integral will result in a specified result (area under the curve). Thanks for pointing this out. Might be worth a video at some point.

[@okaro6595]

My phone did it also immediately. Casio fx-115MS did it in 25 seconds.

[@scottcollins7513]

Phones are incredibly powerful relative to most calculators. Thanks for sharing the info.

[@reinlepiku445]

CASIO fx-991ES PLUS 2nd edition = 13.6 s TI-86 = 12 s CASIO CLASSPAD CP400 = 1.5 s TI-Nspire CX CAS = less than a second CASIO fx-9860GII = less than a second CASIO fx-CG50 = less than half a second

[@scottcollins7513]

Good info. Thanks, Rein.

[@ge48421]

The Numworks calculator does this in a fraction of a second.

[@hackhp]

I just get syntax error when inputting exactly as shown

[@scottcollins7513]

Which calculator are you using? And, double check that you are in the normal calculation mode (vs. imaginary mode, for example).

​@@scottcollins7513 I'm using a Casio 991CW. I deleted the second parentheses after x and it worked

[@leeprimeroessler3277]

If you are looking for speed, there are no alternatives to the Prime.

[@scottcollins7513]

It sure seems that way. I almost called it the 'hp "Optimus" Prime' in the summary at the end because it is such a beast.

[@lemmecheck_]

my cw did that in 1s

[@scottcollins7513]

You have a Casio fx-991CW that did it in approximately 1 second? That's significantly faster than the fx-991EX Classwiz. Impressive.

[@TontonZen]

HP 15C Collectors Edition, full precision (FIX 9) done in about 4.5 seconds. Swiss Micros' DM15 (HP 15C original firmware running an emulator as hardware) running at 48MHz does it in almost 26 seconds. My old HP 42s does it in 49 seconds (similar precision as the HP 15C there at 1E-09) Free42 (an HP 42s simulator) on my smartphone does it instantly on 1E-09 precision, I pushed the precision to 1E-30 and it was done in half a second. Smartphones rule these days.

[@scottcollins7513]

Great info, Tonton. I added your info to the "Leaderboard" in the description. Thanks for sharing.

[@msoushi]

My Casio fx-5800P took only 4.1 seconds. A little bit surprised because it's actually faster than the ES series...😂

[@scottcollins7513]

Thanks for the info -- I added it to the "leader board" in the description. Take care.

[@Rai_Te]

As a referencepoint: The Casio fx-9860gIII is below a second (but not as fast as the prime).

[@scottcollins7513]

Thanks for the data. CASIO fx-9860 GII version is also below 1 second.

[@Fotrex]

Thanks Scott for this precious and fun challenge, my old TI Voyage 200 done in 9 seconds (Mobile 10).

[@scottcollins7513]

I appreciate you sharing your resut. I will add it to the leaderboard.

[@laurenth7187]

My Citizen SRP 350 does it in 18 sec. TI 68 in 16 sec...

[@scottcollins7513]

Good info, Laurent. Thanks for taking the time to share. I need to do this same calc on some of my other calculators to see how they do. When I do I will add it to the description. I may go ahead and compile a little list up there in the description in case people are interested.

[@TheWyattDickson]

Hey, how do you get to the integral function on the Sharp? Which buttons did you press to get there?

[@scottcollins7513]

There are a lot of Sharp variants, but on my particular calculator, I pressed the key just to the right of the Tangent ("tan") key and just above the Natural Log ("ln") key.

[@TheWyattDickson]

@@scottcollins7513It appears that my model doesn’t have this key or function. I just wanted to see if there was a shortcut menu I was missing. Thank you.

[@EmmanuelAsiedu-pp2yq]

What about fx911es plus Casio

[@scottcollins7513]

They do not sell that exact model in the US, but my understanding is that our fx-115ES PLUS is the same (I showed the "2nd edition" in my video). I would expect the fx-991ES PLUS to perform similarly -- in the 14 seconds range. Not great in this respect, but it is still a great little calculator.

[@enigmaticmf]

And for reference, the new Casio FX-991CW is actually a few seconds slower than the FX-991EX... Go figure.

[@scottcollins7513]

Strange. Thanks for letting us know. I've given up trying to understand the TI and Casio calculator product and marketing. It's bizarre.

[@Silanda]

Yeah, this is strange, but I've noticed it too with integration. Sometimes faster, sometimes slower. I wonder if it's got anything to do with the CW's higher internal precision.

[@EricChiEric]

It takes around 5.2 seconds
