Automatic thousands separation in \unit

Automatic thousands separation in \unit

[Marco Patzer]

Hi!

I'm wondering if there's a way to have automatic thousands separation in the
\unit command? \spaceddigits does that, but it doesn't work inside \unit. And
using both would be quite verbose to write. Example:

\starttext
  %% no thousands separation
  \unit{123456789 volt}

  %% manual thousands separation works
  \unit{123,456,789 volt}

  %% automatic thousands separation, but not using \unit
  \let\spaceddigitsseparator,
  \spaceddigits{123456789}\,V

  %% fails, no output
  \unit{\spaceddigits{123456789} volt}
\stoptext

Hi Marco,

Can this give what you wish?

\define[2]\myunit{\spaceddigits{#1}\unit{#2}}
\starttext 
\myunit{123456789}{volt}
\stoptext

Maybe this should be a language specific parameter.  How would you achieve a
similar result with the Indian numbering system
<https://en.wikipedia.org/wiki/Indian_numbering_system> , for instance?

 

Also, decimal and thousands separators vary from country to country.  In
France, for example, they use the comma for the decimal separator, and space
for the thousand separator.

It is an additional feature that may or may not be linked to language. For example, in Swedish originally, the comma and stop are reversed relative English, but in modern times, a stop for decimal point might be used. To avoid confusion between commas and stops as decimal points there is an recommendation admitting both, using spaces as separators. And in India, they might prefer digit groups of two instead of three.

Shouldn’t \spaceddigits use the separator as defined by \setdigitmode and \setdigitorder?

That's a way to solve it, yes. But I'd prefer it to be integrated
into the \unit command. It looks cleaner and I don't have to modify
the sources to use a different command.

Is there a way to hook the \spaceddigits into \unit somehow?

I tried to add \spaceddigits to the \unit command, but it didn't
work. If someone has an idea how to do that, I'd greatly appreciate.
