HP 39gs vs HP 50g - vangelis - 01-31-2017 10:08 PM
Hello to everyone, I am new member here and not an hp calculator owner yet,but this is about to change.After a little research I found two possible buying options. Firstly is a used HP 39gs calculator at 25 euro which is around 27.5 USD and my second options is an also used (but in the box) HP 50g at 90 euro which is about 99 USD. Which do you think its a better option. Thank you for your time !! PS1. I am an engineering student. So far I was using a casio imitation calculator ( not even able to plot any graphs) worthing about 7 USD. PS2. I am not much of rich guy so the 99 USD option would be the savings of the last two months. I am just wondering if it's worthing it!! RE: HP 39gs vs HP 50g - Dwight Sturrock - 02-01-2017 12:47 AM
Algebraic entry versus unlimited stack based RPN entry? It depends on if you are comfortable with RPN. When my HP 34C arrived in the mail (1983) I took it to college and learned RPN while taking a math test- which I passed. Years later I always keep an RPN calc handy. It's so nice not to think about parentheses! RE: HP 39gs vs HP 50g - rprosperi - 02-01-2017 01:54 AM

The 50g is a FAR more capable machine, and has literally thousands of programs and 'how-to' tips on hundreds of websites. The 50g is used by practicing engineers all over the world, whereas the 39gs was built specifically for the High Scholl and College student. While the 39gs can be programmed using 'applets', relatively few of them have been published (compared to 50g programs) however its difficult to compare them as the applets can be more larger and more complete programs including graphing and other features that would need to be built from scratch in the 50g. The 39gs will be easier to learn, partly because it is limited to Algebraic notation. The 50g can use both Algebraic and RPN (actually a variation of RPN called RPL) and, while it does have a steeper learning curve, you will be able to do much more and have better control over your data and programs. Except for educational use, most folks here would recommend the 50g over the 39gs, even thought the cost is higher, because it can do much more and it uses RPN/RPL, which is preferred by almost all HP Calculator fans. Your feedback about these comments and details of your planned use will help to give you better and more specific advice. RE: HP 39gs vs HP 50g - Han - 02-01-2017 03:07 AM

It also has an algebraic mode that makes it behave like other graphing calculators that have similar capabilities. So if you are unsure about RPN notation, don't let that bother you (you can switch between algebraic mode and RPN/RPL mode very easily through the mode menu). This way you can learn the much more efficient RPN entry method at your own pace. RE: HP 39gs vs HP 50g - Gerald H - 02-01-2017 06:26 AM
An advantage of the 39gs is the Sequence Aplet, much more flexible than similar functionalities on Casios & TIs. In general the 50g is hugely more capable & flexible. RE: HP 39gs vs HP 50g - cyrille de brébisson - 02-01-2017 06:55 AM
Hello, The 39g has, in theory the same function set as the 50g (minus the CAS. The HP40g does have the CAS)... However, the 39g is organized in "sectors" where you do specific type of operations while the 50g is much more of an all at the same time system. The net result is that the 50g does allow you to do more, more easely, BUT is harder to use... Now, the Current HP flagship product, the HP Prime is (loosely) based on the 39g. But more expensive (120€)... So, if you are strapped for cash, I would say go for the 39g. However, if you are OK spending 90€... Then you should definitely bite the bullet and spend the 120€ to get a HP Prime on amazon which is significantly better than both the 39 and the 50 (I know, some people will disagree here, let the flame war begin :-() Note, I am working for HP and have been one of the main developers for all 3 calculators (39, 50 and Prime). Cyrille RE: HP 39gs vs HP 50g - grsbanks - 02-01-2017 08:00 AM
If you can scrape the 120€ together then by all means go for the Prime. However, if you need something "now" and you have the 90€ then go for the 50g, without the shadow of a doubt. RPN/RPL is not that hard to learn. In fact, once you get the hang of it you'll be asking yourself why you haven't been using it all your life I honestly couldn't use an algebraic-only machine now. RE: HP 39gs vs HP 50g - grsbanks - 02-01-2017 01:02 PM
As a quick update to this, I've just ordered a Prime from Amazon. Should get it tomorrow (Prime delivery -- no pun intended) and will report back on what I think of it. Edit Feb 2nd... It's just been delivered. The packaging is pretty bad. I think I'm going to spend more time getting the thing out of the packaging than learning to use it...

If the school system does not care or specify which model machine to use, I agree with Han, the 50g is still a better machine (as it can easily use both Alg and RPN/RPL), however many school systems essentially mandate use of Algebraic-only machines, and virtually always teach methods using only Algebraic notation and techniques, in some cases including the 39gs. In these cases, the 39gs is the better choice, as it's optimized for doing exactly this. The Prime is in a whole different class, clearly superior in almost every way to these other choices (RPN being a significant exception) but I did not want to wander out of the options the OP inquired about. Once it's more clear what he wants to use the machine for, it will be easier to steer towards the better choice. RE: HP 39gs vs HP 50g - Marco Polo - 02-01-2017 04:14 PM

All answers have been very helpful. Thank you very much. After some thought I think I will go with the 39gs... In my opinion it's both a better option for an inexperienced individual like me and also an economical one. In the end I thing its capabilities overcome my demands. Right now it's finals period in my uni so after I am done , I am planning on getting a small job to make some money on my own....if things go well I'll be a 50g owner by June!!! I would really like to use this RPN system..! RE: HP 39gs vs HP 50g - jebem - 02-05-2017 06:27 PM

The HP-39gs and its CAS capable HP-40gs sibling are sophisticated calculators that can now be acquired for a modest price. Their only "sin" is missing RPN, but again, their intended audience is different from what many of the 70's old school boys, like myself, used to be. Back then, RPN was the way to go if you had the money to spend on a expensive HP calculator. If not, well, we always had Casio and Texas using algebraic systems. Surely you found it already, but just in case, here are some useful documentation of the 39gs and 40gs: Mastering the hp 39gs & hp 40gs HP 39gs User's Guide HP 39gs Training Modules RE: HP 39gs vs HP 50g - rprosperi - 02-05-2017 07:06 PM

I wrote an aplet that adds RPN to the HP39gs... I hope with this I've absolved the 39 from its original sin... or almost The aplet is written in SysRPL and runs snappy on the HP39gs.
