Calculator App

[atomicthumbs]

Could someone PND up a calculator? The Pandora doesn't really have one unless you count Gnumeric. Slcalc and xcalc both look nice.

How are zx-81's TI emus for the job? Too cumbersome for everyday use?

 

[torpor]

Go to the Terminal and use 'bc'!

I'll be damned. These Pandora tips keep teaching me more about my own desktop.

How about QtOctave or XOctave?

Well I use an HP-48G every day so I probably wouldn't mind, but most people I know are not familiar with RPN (and trust me it does take some getting used to).

Oh didn't notice he had a TI-92 emu. Knew about the TI-99, but I don't think that is a "calculator". Still TI-92 is a lot of buttons if all you need is a simple calculator.

How about QtOctave or XOctave?

Someone on IRC was saying he had installed some form of Octave from the Angstrom feed (repo). This one I think http://www.angstrom-distribution.org/repo/?pkgname=octave

Personally, I'd also like to see Maxima, but I can't find it in the repo. Will have a go at compiling it myself when I eventually have hardware if it is not already packaged up.

bc is difficult

and the TI-92 emulator is hard to use without all the buttons, or some sort of touchscreen keyboard.

I've started to like SpeedCrunch on KDE.
It only depends on Qt, and it seems to be accurate enough, though I haven't asked too much about how it works internally.

What I would like to see ported is Giac/Xcas, a computer algebra system with lots of mathematical functions and libraries. Source is available, and there already is a ARM version available "for some PDA with Linux", so it might even run out of the box, hopefully...

The Author is the original author of the CAS of the HP49G calculators, so you know it's both powerful and efficient. It's like a portable Maple or Mathematica, and would make the Pandora one of the most powerful pocket calculators available. It also helps that it has compatible syntax to TI-89, maple and mupad.

hi,

if you just want a calculator like calc for windows, open terminal and install gcalctool into your pandora-nand:
sudo opkg install gcalctool

no need for a pnd file, its a tiny app ...

I use perl as a calculator:

echo 'function calc { perl -e "print (($1).\"\n\")"; }' >> ~/.bashrc

vitel@x200 ~ $ calc 2+2
4

echo 'function calc { perl -e "print (($1).\"\n\")"; }' >> ~/.bashrc

vitel@x200 ~ $ calc 2+2

This is all wrong.
It should be

echo 'function calc { lua -e "print ($1)"; }' >> ~/.bashrc

I will probably attempt to get QtOctave running on my Pandora if noone else has by the time it gets to me. Always liked using Matlab as a calculator at university.

echo 'function calc { lua -e "print ($1)"; }' >> ~/.bashrc

echo 'function calc { echo $(($1)); }' >> ~/.bashrc

Who needs an external scripting language!
EDIT: doesn't seem to work with spaces though...
EDIT2: oh wait, don't think they'd work with anything else either...
EDIT3: fixed, although * needs escaping...

echo 'function calc { echo $(($@)); }' >> ~/.bashrc

echo 'function calc { lua -e "print ($1)"; }' >> ~/.bashrc

Why not use bash itself :

$ $ echo $(( 2+2 ))
4

Or if using the browser (firefox at least), type this into address bar:

javascript: alert(2+2)

"bc" looks nicer for random calculations when a terminal is handy (that is all work hours for me).

I also like the computer algebra system that Lafazar suggested. Reminds me of the MATLAB and such.

Or if you have Internet and want to offend everyone with your silliness, you could type it into your search engine.
If you have Internet and want to show off, type it into Wolfram Alpha. That site will even do matrices* and graphing if you can get the syntax right.

There's so many ways to add 2 and 2... someone should standardize this.

*Wolfram Alpha pulled my ass through a bunch of boring statistics last year. I can't remember why there were matrices in statistics. I wasn't paying much attention.

open up a Python interpreter...

Thank you, this is exactly what I was after.

Bash does not support floating point calculation.

Are there any TI-84+ emulators around?
I can't be bothered to change batteries in my own.
