\digits get \times instead of \cdot before exponent

\digits get \times instead of \cdot before exponent

[Christian Prim]

[-- Attachment #1.1: Type: text/plain, Size: 495 bytes --]

Hi,

is it possible to change the behaviour of \digits to have \cdot as in
http://www.pragma-ade.com/general/magazines/mag-0003.pdf page 2 (table at
the bottom) instead of \times as shown in the latest units-mkiv-document
http://www.pragma-ade.com/general/manuals/units-mkiv.pdf pages 6&7?

Thanks for your advise
Christian Prim

Example:

\unit{10.5e3 Newton} should produce "10.5\cdot 10^3 N" and not  "10.5\times
10^3 N"

(also tested in the latest version at http://live.contextgarden.net/)

Seems to be hardcoded in phys-dim.mkiv for the moment:

there are several ways we can deal with this:

% \def\digitstimessymbol{\symbol[units][times]}

% \definesymbol[units][times][\times]
% \definesymbol[units][times][\cdots]
% \definesymbol[units][times][\kern.2\emwidth\cdot\kern.2\emwidth]

\def\digitstimessymbol{\times}
\def\digitstimessymbol{\cdot}
\def\digitstimessymbol{\kern.2\emwidth\cdot\kern.2\emwidth}

\unprotect

\unexpanded\def\digitspower 
#1{\digitstimessymbol10\phys_digits_raised{#1}}
\unexpanded\def\digitspowerplus 
#1{\digitstimessymbol10\phys_digits_raised{\digitsplus#1}}
\unexpanded\def\digitspowerminus 
#1{\digitstimessymbol10\phys_digits_raised{\digitsminus#1}}

\protect

or maybe a key/value in setuptimes .. not sure yet

Thanks for the tip Hans,

but the kerning in
\def\digitstimessymbol{\kern.**2\emwidth\cdot\kern.2\emwidth}
should not take place in mathmode, only in textmode. Else the space is too
big. Don't know how to deal with that.

We've already got \setdigitmode, \setdigitorder, and \setdigitspace;
it might make sense to create a \setupdigits to consolidate these
setups into one interface. Something like this:

\setupdigits
   [mode=4,               % -->\setdigitmode{4}
                          % (decimal period, thinspace between groups)
    inputdecimalmark={,}, % -->\setdigitorder{0}
    signspace=yes,        % -->\setdigitsign{1}; '+ 1.4', not '+1.4'
    times=\times,         % or times=\cdot
    ]

Cheers,
Sietse

---------------

P.s: I've been thinking I'd like to write more contexty interface that
doesn't use predefined modes, but lets you setup the decimal mark,
separator mark, the input decimal mark, etc. Something like this:

\setupdigits
   [inputdecimal={.},  % input  3.1415926535
    decimal={,}
    separator=\space,
    groupsize=4,       % output 3,1415 9265 45
    signspace=,]       % +3.14159...

That could even tie into \setuplanguage to allow setting
language-specific defaults. Would anyone be interested in this?

needs a bit of thinking as when we start this route we get lots of new 
keywords (with the danger of introducing inconsistencies) so first we 
need to collect all potential candidates for such keys (e.g. using 
separator might be too generic )

I don't know if it is possible and can not estimate how much work it 
represents but maybe one can consider to merge the digit part of the \digits 
and \unit code.
The \unit command would then use the same code as the \digit one to format the 
digit part. Then, the \unit code would use a specific code to format the unit 
part.
This would make it possible to configure the digit formatting with one unique 
command for both \unit and \digit and another command would be used to 
configure the formating of the unit part.
