No RPN. Neckbeard status confirmed. Calculators are still an unsolved problem for me on glass devices to the point I still religiously carry around an HP50G even though its 6x the size of my phone. Also from some bad experiences, it appears that some "app" calculators are also seriously badly implemented. Even basic trig ops can return stupid values at extremes which makes them untrustworthy. Plus none are reasonably…

I just replaced the batteries in my 48GX. I think in stacks and RPN is a better system for how I think. I have 48GX emulators for my phone and still use them over more modern calculator apps. That being said, I appreciate the design considerations they've applied to this. I wish they'd make an Android version, because I might have been interested in trying this out.

Graphing functionality on a phone reminds me of an old TI calculator. I really don't know why recent OSes (be it on PC, smartphone, tablet) always came with such feeble calculators. It's not like TI calculators are difficult to use. Sure if all you want is add/min/mul/div functionality the TI is essentially a traditional calculator, and then behind that you've got all these nifty graphing utilities. It's not like a g…

On that note, iPad doesn't even have the iPhone Calculator app, and it's _impossible_ to get it (without hacking) because it's a built-in app; one you cannot remove nor acquire from the App Store. It's also missing Compass, Voice Memo and Passbook apps. Edit: Weather app too.

yes weird, plus the weather app is missing too.

What's the reasoning behind the decision? Was it Steve Jobs who decided that?

This looks closer to Mathematica/Maple/MATLAB than a basic calculator, although still nowhere near the power of those. Of course 1/0 should be +Infinity, not ?... (Disclaimer: I have a Mathematica console always open on my desktop, and regularly use it for all kinds of calculations.)

Why should 1/0 be +Infinity? Think of 1/x at the limit as x->0 from the left and from the right

I still think the 1/0 problem can be solved if we step outside Euclidian geometry. It is undefined for the very reason you give. The Numberphile YouTube channel has an excellent video [1] discussing why x/0 is undefined and worth watching.

And now for the majority market share, the android version?

Just because an OS has a "majority market share" doesn't make it a suitable market. Elegant, minimal premium apps like Clear have done well on the iOS app store, but it's hard to imagine a $5 calculator app getting much interest on Android.

Why is that hard to imagine? If the application were released for Android, I would have considered it. I've already purchased several Android calculators. There's no real basis for your claim, but I say this while I also realize I haven't provided sufficient evidence to support why Android would be a better platform. The reason I think a lot of applications like this fail on Android is that the developers first target iOS and then try to port it to Android without really designing for Android. The result is something lackluster that doesn't really work for Android devices.

Just a musing: perhaps its considered not as valuable an investment to program since a (the?) primary market is students, and students are probably not allowed to use phones on tests for obvious reasons (internet connectivity, texting questions to each other, overall distraction). However, TI's are state approved or whatever.

I'm working on an RPN calculator (with some pretty sweet gestural functionality) which solves approximately half of those problems. Wait, no, more like a quarter. Welp.

It does return the correct value for sin(π) though (you gotta call __sinpi(x / M_PI) if you don't want to return -8.74e-8 or some ridiculous value).

Haha! I was going to suggest Droid48 until that last sentence. Yes, I emulate my HP48G whenever I feel the need to fire up a calculator.

HP RPN can't be beaten for serious number crunching. It's not pretty, but by god, it is EFFECTIVE!

They just haven't created the full size iPad versions for them at this time. iOS 6/7 added some previously iPhone-only built-in apps.
