Handheld calculator that for binary/hex/logic
« on: September 28, 2016, 03:16:42 am »
Is there any INEXPENSIVE calculators out there that do binary, hex, and bit logic  well as the usual stuff you get in a scientific calc? I basically want the computer science calculator that comes with Windows 10, but in hardware form. I use that one constantly, but desire the convenience of an actual handheld.

Define inexpensive. I've got a bunch of Sharp EL501XBWH in various places, they are cheap enough and work and feel good enough for my taste.

That would do allot of what I want, and it's definately  in the price range I like.  What it lacks that the Windows app has is bitwise logic functions. Sometimes when I'm trouble shooting, it's nice to have that to make sure what I think an operation should be doing is right.

A large enough screen such that both operands, and the result can be seen at the same time would be nice too.

I think $50 is as much as I'd want to pay for such a thing, roughly.

The Casio fx-115MS will do all the usual bitwise operations. Its interface for them is OK but not fantastic... but hey, it's $12 or something similarly ridiculous.

There may be other more suitable/newer/cheaper models out there, but that's the one on my desk right now and it will get the job done.

If you have an Android phone, you can search for a "programmers calculator" in the Application Store. There are a few HP calculator emulators like HP 16C, too.

I use RealCalc (Plus) on Android. I like it a lot.

For a physical calculator, TI's top end scientific (non graphing) calculator has what you need.

TI-36X Pro, $19 on Amazon. Even has hex letter keys :-)
(note: the similarly priced Casio fx-115ES PLUS also does it - in case you are more of a Casio guy).

BTW, fun fact about the Windows calculator which tricked me a couple of times: in the default "Standard" mode, it doesn't do proper operator precedence, it does fully left to right instead! (i.e. 1+0*100 =100)  :scared:

You have to put it in "Scientific" mode to get proper operator precedence. Fortunately, it's a sticky setting, so you won't get back to the crazy default mode unless you choose to.

The cheapest calculator is inside your skull, and also the fastest once you get enough practice with it. ;)

I don't think any calculator which doesn't show the expression being entered should try to do things with precedence, as it gets confusing otherwise. A standard calculator should be used more like an accumulator machine.

Wouldn't the HP 16C be the ideal calculator?

Available here as a clone: https://www.swissmicros.com/

Unfortunatly a little expensive...

AFAIK Casio has (or had) some calculators like that. I have a Casio fx-115MS which is an older model you can still find new on Ebay like this one:

There are small lies, big lies and then there is what is on the screen of your oscilloscope.

Works for me.

Well, maybe I started too late in life. Took me better part of 10 years working with hex and binary before this could be said.

I like the powerone calculator in my iphone, I've got for $5 or something. it does all sort of calcs included hex and binary.
you can also get a hp 16c emulated on the phone that's nice (and about the same price)

It's not very accurate or reliable and it doesn't do logarithms or trigonometric functions. Plus the solver is a bit wonky on mine.

Here's a free emulator to run on your PC.
http://www.wrpn.emmet-gray.com/Downloads.html
I have tried it ( the java version on linux ) seems rather nice. Looks just like an HP16C. Very well done, good documentation too.
 There are various versions for Windows and Mac/Linux (in java) and an Android version, too.  The source is available in C# so it perhaps could be ported to run under mono on Linux.
Download it and give it a try.

If you want a "real" one to hold in your hand, a group has made a small reproduction one herehttps://www.swissmicros.com/#DM16 / DM16L as well as reproductions of some other classic HP calculators.

Used HP-48G calculators can be had for very reasonable prices on eBay. Perhaps the pinnacle of HP calculators?
