Scientific Calculator, RPN
 

I would love to find a scientific calculator application for my BB8700, especially one that allows reverse-polish-notation (RPN) entry, something like an HP 32S / 42S etc... is there something available?

The calculator app that comes with the 8700 is okay for basic stuff, but there are no trigonometric, exponential, or other useful functions... and its precision is very limited... try entering anything beyond 99 million... to enter 128 million, you need to enter 12.8 million, then multiply by 10.

Still in Beta?
 

I was looking for exactly the same thing and one of the users in this forum, patrickh, sent me an app he was working on about 7 months ago. It works well, some minor display inconsistecies, but I never heard from him again. Anyway, I have it on my BB and it is the only caculator I use due to the RPN. Patrickh, if you're out there, any update for us?

I am still here.. I just have no time to work on it.. What update/feature do you need?

- P

got it!
 

Patrick got me a copy, thanks a million, this is a big improvement over the calculator that comes with the BB, and it uses RPN entry!!!!

Way to go, Patrick! (y) (y)

Where can one find this RPN calculator? I would like to download and checkout.

Thank you,
K

I've got a bunch of engineers here that would be giddy to get a decent RPN calculator on their blackberries. Any info would be greatly appreciated.

Add me to the list of those interested in RPN. Any link to this app?

I PM'ed Wrenfroe and ifonline with the link.. send me a PM if you want to be on the beta..

P

Thanks... got it... trying it...

The calculator is awesome. Outstanding work! Thank you.

Please send me a link. Thanks!

Please send me a link. Thanks!

There are some free tools out there, guys! Check out this one http://www.bradgoodman.com/blackberry/ -- scientific calculator, engineering calcuator, triginometric calculator - and more! so far the best though not 100% user-friendly.

I would really love to have an RPN scientific calculator, thanks
 

Also, does anyone know of a good simple FREE Financial calculator too?

I'd like to get on you beta list also, been looking for a RPN calc for my BB.

Awesome, makes me wish I would use it. Good luck on the app Patrick!

RPN calculator
 

I've been searching for an RPN calculator (preferably one that feels like one of the HP models). How can I obtain/purchase a copy?

BTW, I currently use Bizmathica from ShrunkenHead Software and it works fine...does financial math as well as trig, etc., however it is not RPN.

PM me for beta of my RPN calculator.. It's a scientific / engineering / programmer's calculator rather than financial.

I'am new to Blackberry, I downloaded the rc.jad file for the RPN calculator, but how do I get it into my Blackberry 8700?

Jad files are meant to be loaded OTA, unless you convert it ot a cod file (There are threads here that do cover how to do that) you will not be able to download it via the desktop manager.

If I could get a beta version that would be great.

I would be most interested in the beta, too. I've never figured out how to work those calculators with the "=" keys. ;)

can i get the link also

mee too!
 

I'd love the link as well. Thanks in advance!

access the link from your blackberry rather than your desktop. .jad files are OTA downloads directly to the handset. Slick, huh?

RPN Calculator Beta
 

Would like the link for the RPN calculator. Have an 8700c and can download from a phone browser link with a .jad file, if it's available.

Thank you. (Wish I knew what "pm" meant).

Link?
 

May I get the beta rpn link as well?

I also would appreciate it very much if you would share the RPN calculator with me (for 7290). Thank you...

Also interested in the RPN calculator for 8700... thanks...

could i get a link for the calculator too. Thanks in advance

I would also like a link for the calculator for BB 8700. Thanks!!

Me too please! Could I also get a link for the calculator? (I have a 7130e) Thanks!!

RPN link request
 

I'd also like the link for the rpn calc. Using a 8703e Verizon.

I would like to have a link for RPN calculator too for my 7130e please! :) I have been using HP RPN calculator for 20 years.

Please PM me if you want to be on the beta..

There is now very limited support for complex numbers and support for Pearl. Plus a few changes reported by beta users (like you can no longer enter -123 as "negative 123". You have to do "123 neg" or "123 _" to be more consistent with HP calcs.

- P

I would be all too happy to try the calculator. I am new to the forum, so advice on how to PM would be great.

Thanks,

Kelly

If you click on Patrickh's user name in the message above yours, there's a link on the drop down menu to send him a Private message.

May I have the link for the RPN calculator too? Any beta or help with anything related to RPN, please do not hesitate to contact me.

Hello Patrick. Can I also get the link to the RPN calculator? I just purchased a blackberry device (8703e) and I would love to integrate an RPN calculator on my new device. Thanks!

Speaking of calculators, does anyone know of a Financial calculator like the HP 12c?

please send me a link. (Q@Dreesmann.com)

Thanks,

I'm interested as well...
 

As a life-long (pretty much) RPN user, I find it exteremely difficult to use an algebraic calculator.

Kurtis

can i get the link too please?

Lygea, Welcome to Lygea Calculators makes HP emulators. Their emulators for PPC are fantastic, and the one for BlackBerry is promising. It's only the HP 10B, so no scientific functions. But I am keeping an eye on this group hoping that something comes soon. The HP 10B is NOT RPN for some reason...

Another avid rpn user
 

Hello Patrick. Can I also get the link to the RPN calculator? I just purchased a blackberry device (8703e) and I would love to integrate an RPN calculator on my new device. Thanks!:smile:

I've been watching the Lygea site as well, hoping that they'll come out with an HP15C emulator for the 8700.

My RPN calc is still in beta.. sorry no time to work on it.. but it is quite functional.. PM me if you want to try it out..

P

Would you send me a link to the RPN calculator for Blackberry, Thanks in advance

May I get the link?

thanks a lot!

Patrick,

I would appreciate the link as well - PM is fine.

Thanks,

I just bought my first Blackberry and am looking for an RPN scientific calculator. (Before I had been using a Palm with a Creative Creek Mathu Pro).

I would appreciate very much a link to your beta RPN to make my Blackberry complete.

Thanks in advance.

I would love a link too, please?

Patrick, is there a way to stay up to date with your calculator? Works flawlessly for me.

Best,

How to install rc.jad?
 

Hi, I have received the "rc.jad" file, but the software installation function of my BB desktop does not want .jad files and does not accept the rc.jad file when browsig in *.*-mode.

Sorry, this is my very first installation ;)

Thx
Thomas

PS: I have a 8700g (T-Mobile)

Would love to get a copy of your RPN calculator as well.
Thx in advance!

Can someone just post the link here...?

Thanks

Patrick, can I be another lucky recipient of your RPN calculator for Blackberry 8700?

RPN calculator for 8700c
 

patrickh, I'd love to get the link to your RPN program -- I just broke my last HP calculator and am struggling with the standard one on the 8700c...

Thanks,
Matt

I'd like to be on your beta program too.. I am a college student with a need for a hardy calc..
Can you please send a link to the address below?
Thanks in advance!

Hey, it's in beta.. Why don't you just PM me for a link like everyone else here?

RPN Feedback
 

patrickh, the RPN functionality is great. Here are a few suggestions:

+Keyboard operation: Needs to execute when an operator is entered via the keyboard (ie 25 (enter) 10 + should immediately return 35)
+Keyboard entry for other functions (ie, quick access to ^, etc)

Additionally, check out: Pocket 12C SE Financial Calculator. They make a Blackberry product as well, but not RPN.

It is amazing to me that there is not a developed RPN calculator for the blackberry. This exists for the Treo, but the blackberry has 8 million subscribers, and I would guess 90% of whom are users of hp12c's or hp 15c's. Seems like a prime business opportunity to me.

Thanks!

You can sym-o to get to ^ on a qwerty..

Yes.. execute on operator.. when I have time.. In the mean time you can enter something like 1 2 +<enter>

Can I have a copy too? I am new here and I dont know what is a PM... But I really need a RPN calculator.

Forward notation is so confusing!

Hi Patrick,
Can I have the link to install the RPN calculator??
It will help a lot...

Update?
 

Any new version of the project?

I, for one, am happy to make a substantial financial donation to spur development.

RPN Calculator Link?
 

Could someone please send me the link to the RPN Calculator for my 8830?

patrickh, I don't mean to hijack your thread, but while I was looking for an RPN calculator with financial functions I found this:
SourceForge.net: HorsePower Files

It's not blackberry specific, but it actually works rather nicely on my 7100. Looking at the source, it appears they use images for the red LED digits in the display instead of fonts -- very cool!

I like the command-line style entry which you use in your calculator, as opposed to the button-emulation style used in theirs. Perhaps you could incorporate their LED display and financial functions?

Anyway, I just wanted to encourage you to keep working on the calculator and thought this might give you some ideas.

Anybody heard from patrickh lately?

You OK there?

Yesyes.. still here.. just busy :) Yes.. Financial functions are cool.. I will see what I can do..

Glad to hear you're still alive!

Two primary requests:
-Functions execute on operand
-Formatting (1,000,000) would be nice.

Ben

Please, please, please!!

Do a bit more with your calculator!! I don't do a lot of heavy math, and if you made a few small changes the calculator would be most of what I need. As requested earlier in the thread, making the math execute immediately (25 {enter} 3 {+} (result)) would make the feel "exact" to traditional HPs. If you also made the existing functions keyboard mapped, I (and I'm sure many) would have most of what we need.

Just got it
 

Patrick, thanks so much for the link; it works great on my 8830.

Is there a way to make the command buttons on the bottom take up multiple rows instead of scrolling?

Thanks,
Will

Yet Another Beta Tester
 

patrickh...I, too, would love to have your rpn scientific calculator. I bought my first HP in 1973 (HP 35), the one with the error in the "exp of ln of 2.02" (returned 2.00 instead of 2.02). I've owned an HP 41C, an HP 15C and an HP 32S II. Still have all but the 41C, which crapped out. The sweet spot was the 15C. Have used PalmCalc on my Treo 700P, but now have transitioned to a BB 8800. Having withdrawal. You're a saint, by the way. ...Jack

Wirelessly posted (BlackBerry8100/4.2.1 Profile/MIDP-2.0 Configuration/CLDC-1.1 VendorID/102)

Ahhh, the 15C. Why HP doesn't still sell that one is beyond me.

patrickh, I would also appreciate a link to the calculator. TIA!

This thread has long legs, but then, so does RPN.

[Edit: PM sent.]

RPN for BB
 

Patrick, please email me the link for your RPN calculator. I'm happy to provide feedback if you are interested.

Cheers and thanks in advance.

Looking for the chance to try your RPN calc

Lygea Released HP12C for QWERTY BlackBerry
 

Lygea Welcome to Lygea Calculators just releases a version of the HP12C for BlackBerry. I tried it and liked it.

Too bad it's not the 15C scientific calculator. And it doesn't work on the 8100 like the 10C does. But glad to see RPN though.
