Scientific Calculator

I would be grateful for a scientific calculator as a portable app. There is Xcalc but this is reverse polish notation/HP which is difficult to use compared with DAL logic. I know it's only a question of what you're used to by HP style takes some getting used too.

thanks

Yup.

It's gonna be a launcher for Microsoft's Calculator, which is also a scientific calculator.

Who needs that

I believe it would work if ya found the .exe that opens Microsoft Calculator, just copy it to your thumbdrive and use Reshacker to make it PAM friendly, (product name change). I have done this for other Windows utilities like regedit and the Task Manager.

That's basicially...

What it is. I just used the launcher from John's On-Screen Keyboard Portable. Sure, it's not completely nessesary, and it's gonna have some extra uneeded things, but it'll have a splash, and be in .paf.

Then people will have a calc in there menu, without going to all the trouble you just said.

I know...

But I just made it so you can launch ift from the PortableApps Menu.

Would this one Work?

I might check it out later.

Nice.

That one's nice. I was looking for a good open-souce calc. But I couldn't find anything good. I should try to do that one. But I don't know how to make the program run without an install.

TTCalc is in two versions.

TTCalc is in two versions. One is an installer and the latter is a binary package (ttcalc-*.tar.gz).

Well...

I made it portable. Where did you see the source? I can't find it.

Take a look at SpeQ

Speq is not exactly a "calculator" but is an awesome math program. You just type your formula on the sheet. It does fractions, algebra, graphing, etc. Works great portable, though can't guarantee that it meets the stealth requirements of some.

Scratch TTcalc

Couldn't get UniversalExtractor to unpack it. Someone else might have better luck. The source is also offered, but I wouldn't know where to start.

TT-Calc

Thanks i'd overlooked this one. I think i've tried it before and forgotten about it. It has an installation .exe and worked fine. Not sure what this universal extractor is - i just download and use 7-zip when necessary. It is very good just shame it's not portable. Xcalc is very good for the few who can cope with the 'reverse polish'/HP notation. I can't.

Why is everything on sourceforge.net so slow to download?

Graphcalc

i recommend it. its a scientific calc and graphs 2d and 3d functions. actually pretty simple for what it can do and runs fast. also, its open source.

Website:
http://www.graphcalc.com/download.shtml

also look at this to make it purely portable:

I would love

to see a portable Calculator.
That's one thing I love about my Microsoft keyboard:
It has a shortcut key right ontop ot the numbers to directly open the calculator.

Well right now.

The launcher I changed works fine for launching Microsoft's Calculator. I have it in portable apps format. And I have the splash done. (Two infact, and the icon changed.) I even have one version zipped up in a self-extractor, it's just there's lots of uneeded script in there, so I'm trying to take out the uneeded stuff, but keep the launcher working.

Almost like a portable lite version of Matlab. Brilliant App! I do all calculations using it.

Does anyone konw, how to contact the autohr of Eigenmath?
1. Eigenmath does wrong with sin(0)/0. Since Eigenmath can do sumbol calculte, I think it is not too difficult to calculate
sin(0)/0=lim(x=0)(sin(x)/x)=lim(x=0)(d(sin(x))/d(x))=lim(x=0)(cos(x)/1)=cos(0)=1
2. If Eigenmath could support much program flow control(IF...THEN...ELSE END) and defining of complex function, it must become the ONE!

Wrong.

You are calculating the limit when x APPROACHES 0. This is not the same than the value when x IS 0. That is a kind of discontinuity that can be "fixed" by using a different function defined as

f(x) = | 1 if x=0 or
| sin(0)/0 if x =/= 0

But f(x) is not the same as sin(0)/0.
A related example: 1/x has a similar problem, but since the limit is +infinity if you're coming in from the right or -infinty if you're coming in from the left, you can't fix it. Neither can you "fix" 1/abs(x) which's limit is +infinity from both sides.

Now stop torturing all us innocent people with Calculus!!!! What have we done to deserve it???!!!! Smile

Don't worry

If you are unlucky enough in your last years of highschool, they might try to stuff some of that into your head. If you get a bit lucky (and study law, or archaelogy) you might even live a complete life without learning that. Some people have been known to even manage to find a wife without knowing that! Smile
But some of us have been veeery bad in our past lifes. Sad

actually...

if f(z) is defined as:
f(z) = sin(z)/z, where z is a complex number (ie. z = x + iy, i^2 = -1)

f(z) = (1/z)(z - z^3/3! + z^5/5! - z^7/7! + ...) [Taylor expansion of sin(z)]
= 1 - z^2/3! + z^4/5! - z^6/7! + ...

This expansion converges on the whole complex plane, implying f(z) is an entire function, and f(0) = 1

(no limits here... f(z) = sin(z)/z implies f(0) = 1)

I just thought of reading this like snoop

fzizzle equals sininizzle by sizzle to the z degree

fzizzle equals a low rider zizzle taking 3 by 3 spread with high five sizzle, by the seven. etc.

hey, maybe this will actually get people to appreciate Calculus...

fo shizzle my bizzle, pull out yo eigenvizzle
gimme zero zero zero like auto 9 millimizzle
