math punctuation

math punctuation

[Hans Hagen]

Hi,

Since math punctuation was on my todo list anyway, i added it to the core. 
Instead of the hard codes stuff, i made them proper math symbols.

By default we have now defined:

\startmathcollection[default]

   \definemathsymbol [mathperiod] [ord]   [mi] ["3A]
   \definemathsymbol [textperiod] [punct] [mi] ["3A]

   \definemathsymbol [mathcomma]  [ord]   [mi] ["3B]
   \definemathsymbol [textcomma]  [punct] [mi] ["3B]

\stopmathcollection

and:

\definemathpunctuation . mathperiod textperiod
\definemathpunctuation , mathcomma  textcomma

which means that

\enablemathpunctuation % can go into cont-sys.tex if needed

$(1,2) (1, 2) (1{,}2) \hbox {foo, bar}$

give the desired results.

This will be available in the next beta.

I think that adding ; and : also makes sense, but i first want to know what 
the french requirements are,

PS. For the real hackers among us: one can swap comma's and periods in math 
by saying

\definemathpunctuation . mathcomma  textperiod
\definemathpunctuation , mathperiod textcomma

Why should you? Well, I could imagine an existing input file with the wrong 
decimal sign, which could be changed in this way, provided all numbers are 
in math mode. If it could be of use for a normal user: What are you 
thinking of?

converting non continental numbers into continental ones: 1,000 => 1.000

but for that purpose, there is already \digits

That kind of input is precisely why I like this feature. :)
