Dezimalkomma

[Wolfgang Werners-Lucchini]

Hallo,

if I write $0,8$ the distance between the ',' and the '8' is too big. 
I can write $0,\!8$ or an other kern, but I don't see how I can write 
a macro to avoid the extra effort.

Shouldn't be this gap in german (\mainlanguage[deo]) as big as $0.8$ 
in US? Is there a switch I have overseen?

-------------------------------------------
\mainlanguage[deo]
\starttext
$0,8$

$0.8$

$0,\!8$ 
\stoptext
-------------------------------------------


Thank you

Wolfgang

Thanks! I have always used $0{,}8$ which is not very elegant.

indeed, and as we often need coordinates in schoolbook math the 
automatic features is there now

(there will and can be more such math goodies so don't hesitate to 
collect them)

I wrote about it some time ago, but I have deleted that email, so here
is the thing again.

In the Polish typesetting package for LaTeX, there are defined a few
commands like \tg and \ctg, since in Poland we write "tg" and not "tan",
and "ctg" and not "cot".  (There are also a few more commands, like
\arcssin generating arc\,sin etc. according to Polish customs.)  I know
that this is controversial, but it would be nice to have a switch so
that \tan also produces "tg" etc.  The reason behind it is that if we
treat TeX as a markup language and not a typesetting one (as is often
the case with mathematical formulae), we want to be able to adapt to
local typesetting traditions without changing the code.  Also, cutting
and pasting formulae between Polish and English texts (and I need it
from time to time, for example) would be easier that way.  I agree that
this need not be the default, but having it as an option would be handy
(although not really indispensable).  Would such a switch be possible
(without too much work, of course)?

And BTW: Hans, your post in the topic about docs for ConTeXt was *very*
interesting.  I am going to put the link to this thread in the archive
onto my personal blog.

some things are easy (and can be written in parallel to watching a 
movie) ... in the beta ...

\starttext

     $\tan{x} + \cos{x}$

     \mainlanguage[pl]

     $\tan{x} + \cos{x}$

     \mainlanguage[nl]

     $\tan{x} + \cos{x}$

\stoptext

currently no special switch for math so it goes with mainlanguage (but 
one can overload \mathlabellanguage)

see math-lan.mkiv ... up to you (and others) to complete it

Is there some sort of a standard for the abbreviations of such functions? 
Does the standard just depend on your main language, or does it also 
depend on a particular field?

Depending on that, we should either switch the labels based on the main 
language, or using a \setupmathematics switch.

Hi,

The matter of abbreviations for mathematical functions depends on countries, or maybe on languages: in French, somewhat like in Polish, the trigonometric functions tangent, cotangent are denoted as \tg, \cotg, and \arcsin is printed rather as arc{\,}sin. So the solution pointed out by Hans works fine (it is something like \quote{} which yields different quotation marks depending on how \mainlanguage[] is set). I just tested the example given by Hans with the latest beta… (indeed only in mkiv, since mkii is frozen).
Eventually maybe the best solution would be to have
\setupmathematics[mainlanguage=pl]

Best regards: OK

indeed, but i want to wait woth that till we run into more language 
dependent issues (as we might need to distinguish between label like 
things and typesetting)

i've seen tg being used in nl as well so it might be an european thing

let's just collect them and then see what further action is needed

(fields is indeed another issue)

You need mkiv for
\setupmathematics[autopunctuation=yes]
to work: on the Garden your file is processed by mkii.

This only works with MkIV. The garden currently just supports MkII.
