TeX, LaTeX and Friends

Hi, how can I debug for this error in tikz:

Dimension too large.
<to be read again>
\relax
l.43 }

Im already using the `fp` package and `fixedpointarithmetic` as tikzlibrary and as key in `\tikzpicture`. I can't think of a way to determine whether my calculation is too hard or if it's something else...

Or, for the mathemagicians out there, a workaround would be to not use the series expansion but instead a closer apprximation to the omega function? :-)

David Carlisle

@1010011010 can you not scale your function to keep values below \maxdimen ?

1010011010

@DavidCarlisle Using \pgfsetmacro which allows no arguments as far as I know? Or do I just set the key locally when I use the result of that calculation ?

David Carlisle

@1010011010 I have no idea if pgf has a key for it (I have no idea about pgf at all:-) , I just meant adjust your expression so that instead of plotting f(x) modify the formula for f so the values are say a factor of 1000 less, if that works, you can fix up the axis to reverse the scaling

1010011010

\pgfmathsetmacro{\result}{\ik-(\ik^2)+(1.5*\ik^3)-(2.66666667*\ik^4)+(5.2083333‌33*\ik^5)-(10.8*\ik^6)+(23.34305556*\ik^7)}

Funnily, this is fine: ` declare function={gamma(\z)=
2.506628274631*sqrt(1/\z)+0.20888568*(1/\z)^(1.5)+0.00870357*(1/\z)^(2.5)-(174.2106599*(1/\z)^(3.5))/25920-
(715.6423511*(1/\z)^(4.5))/1244160)*exp((-ln(1/\z)-1)*\z;},`

Nope. Absolutely no way to make it work right now. Checking out.

@1010011010 Honestly, TeX is not the place you want to do a huge number of complicated calculations in, fp or not. Can't you precalculate the function values and store them in a file?

@cgnieder Thanks a lot.

@cgnieder The same users are fighting again over at TeXWelt. Amazing.

@Johannes I know. Every time I promise myself not to say anything... but I couldn't resist. I never really understand what the problem is...

Johannes_B

@cgnieder I don't know. I really don't.

@cgnieder Sometimes my posts can be read as if i am sitting at the keyboard, aggressively hacking something down. Same goes for Ulrike :)

But often i am just calm.

Q: Are there many journals that do not accept TeX?

I have been told by our head of department, a veteran academic with a lot of publications behind his name, that I am not allowed to write my masters dissertation with TeX, as many journals do not accept TeX documents, and now I have to use Word. I can almost not believe that journals would prefe...

Sometimes I underestimate the bias of NonTeXnicians which says something about me too :)

@1010011010 You need fpu library for that.

Q: What is the probability of 4?

I would like to know with what probability the number 4 appears in the grid of the game 2048. As well, is this probability the same at the beginning? I tried to find the original game's source code, but I did not succeed.

@StephanLehmke I am making complex animations of complex graphs. I'll be struggling to externalize it without awkward end results. :-)

@percusse Thanks again for your help on the LaTeX3 thing. You left in a hurry so I figured it'd be appropriate to give you some notion. :-)

percusse

@1010011010 My pleasure. Work calls again for example :)

I use it as a break at work to fiddle with TeX but it's very limited time-wise

1010011010

You're allowed to install TeX at work . . . ?

@1010011010 Sshhh.... :)

On another note... intersections with surf plots. What am I getting myself into? There's this tex.stackexchange.com/questions/52953/… and this tex.stackexchange.com/questions/73922/… but both are basically complicated and all I want is to intersect at one point. :-(

Just a matter of setting a variable height at a set point ? There's no way to actually intersect?

Stephan Lehmke

9:42 AM

@1010011010 Animations mean even more number crunching. Why is it more complicated to pre-calculate the function values for all parameterizations which are part of the animation? Sounds like a simple multidimensional array to me.

1010011010

@StephanLehmke I have an on-the-fly solution that works for me. I've tried externalization (mostly with GNUplot) and I ran into so many new things that I had to read into that I just went with what I had at that moment. Next document will have your pre-calculated values, promise. :-)

1010011010

10:02 AM

Oh I may know the issue now.... my calculations work so long as I keep the result of the calculations between 0 and 10. haha

Must be some truncation issue.

En route to SP. Half of the public transportation is on strike. Heavy traffic jam, 250km. Cold and with rain during the day. My flu is back. No TeX distro in my tablet. Oh joy.

Heiko Oberdiek

11:29 AM

@DavidCarlisle What is the hidden feature that \@textcolor uses curly braces instead of \begingroup and \endgroup for making a group? The curly braces disturb math spacing, because they act as \mathord.

\def\@textcolor#1#2#3{\protect\leavevmode{\color#1{#2}#3}}

See tex.stackexchange.com/a/85035/16967 or tex.stackexchange.com/q/183471/16967

David Carlisle

@HeikoOberdiek well it's supposed to be like \textrm

Paulo Cereda

I am freezing to death, help!

David Carlisle

@PauloCereda burn some vim manuals to keep warm

Paulo Cereda

@David: is there a vim manual? :)

David Carlisle

@HeikoOberdiek I think we had versions of \textxx in early 2e releases (or it may have been latex209-NFSS) that used \begingroup but I think users complained they couldn't do x^\mathrm{a} or something. (Probably textcolor should have used begingroup....)

Heiko Oberdiek

12:13 PM

@DavidCarlisle x^\textcolor{red}{a} is not working because of \leavevmode already.

David Carlisle

@HeikoOberdiek yes I know. I'm not sure if I can change color, could ask that xcolor changes, or do you think that incompatibility there would be worse. Not sure (I hate change, it always breaks something:-)

Heiko Oberdiek

With \let\leavevmode=\relax it would be working, but the \aftergroup color whatsit would go after the superscript and a following subscript would be misplaced.

@DavidCarlisle It would break xspace: } and \endgroup are different for \xspace :-(

FionaSmith

@PauloCereda FSmith the non-TeXBot: @DavidCarlisle 1 @egreg 0

David Carlisle

@FionaSmith :-)

@HeikoOberdiek That's a rubbish package anyway, who wrote it?

@FionaSmith if you don't want to make the box an exact fraction of the page width, and you want to centre the result, change flushleft to center and add {} {} as many as you need, with spaces between to make empty cells to fill the last row. (to do it automatically you'd need a counter and to know how many entries you'd set in the list and then some arithmetic to know how many padding cells you need, but doing it manually is easier:-)

FionaSmith

12:40 PM

@DavidCarlisle yeah, I could do that, but it rather ruins the "cut and paste long list of numbers into my document and automatically get a table". It looks fine with 12 columns and my numbers will never have more than 4 digits so I'm happy :)

Heiko Oberdiek

@DavidCarlisle :-) I found a workaround for my answer (tex.stackexchange.com/a/183496/16967) by using \begingroup and \endgroup in math mode only.

David Carlisle

12:53 PM

@FionaSmith well I could add teh counting code but if you are happy with the makebox[\textwidth/8] approach and flushleft, I won't bother:-)

FionaSmith

1:05 PM

@DavidCarlisle if you're feeling bored I won't complain if you update your answer! I might have done it, but I don't think I'm up to the coding task myself. TeX is all still very mysterious to me... basically it doesn't look like Fortran!

Johannes_B

@DavidCarlisle The inputenc/cyrillic question seems weird

David Carlisle

@Johannes_B yes can't say I've measured recently but I'm surprised if it's really noticeable (especially not in a real document that's doing graphics and indexes and stuff) Of course it affects Cyrillic more than (say) German as it's almost all the letters rather than just the accented ones, but still....

@DavidCarlisle eew not that kind of fortran ;-) Thanks for the fix - I suspect I'll stick with the one-liner though. It's just too neat to tamper with.

Hello all

2:56 PM

@DavidCarlisle I've TeX macros with up to 50 arguments here; do I qualify for something with that?

1010011010

Hi.. any GNUplot experts here? OR mathematicians in general? I want to calculate a range of critical values by using either the incomplete beta function or the hypergeometric function (I'll just rewrite in expressions of x=<something something related to degrees of freedom>)... I feel really really damn stuck. :-(

In GNUplot I can't find anything relating to the implementation of ibeta?

David Carlisle

3:24 PM

@StephanLehmke nah not #50 though, 10 nested macros with 5 arguments each doesn't count:-)

Stephan Lehmke

@DavidCarlisle Now I'm tempted to write some sort of preprocessor just for this :-)

@egreg: Un gruppo di investitori, scrive sempre il portale tmw, sta lavorando per poter far disputare Napoli-Juventus in Brasile, nel nuovo stadio del Palmeiras che sarà pronto entro due-tre mesi. Il Palmeiras è una società italiana (fu fondata da immigranti italiani nell'agosto del 1914), quest'anno fa 100 anni di storia e alcuni intermediari stanno lavorando alla possibilità di far giocare la manifestazione nel nuovo impianto sportivo.

Yay!
