Feature request: \digits command

Feature request: \digits command

[Morgan Brassel]

Hi everyone,

The \digits command is really great when it comes to typeset numbers in 
different languages. However, I miss one functionality from the numprint 
package in latex: when you type for example $e-5$, you get 10^{-5} (with 
no dot in front of it).

Would it be possible to add an option to \digits to reproduce this?

Best wishes,
Morgan

\starttext
\def\digitpowerseparator{10}
\digits{e-5}
\stoptext

Thank you, Wolfgang.
I have already read the "This Way" on your link very carefully.
In fact, I was looking for a solution to have
\digits{e-5} printed as 10^5
\digits{2e-5} printed as 2 . 10^5
Is it possible to do that? to detect if there is a number before the 'e' 
in \digits?

Regards,
Morgan

\def\digitpowerseparator
  {\ifx\collecteddigits\empty
     10
   \else
     \cdot10
   \fi}

\starttext

\digits{e-5}

\digits{2e-5}

\stoptext

Great, thank you!
Maybe this should become the default for the \digits command?
Or at least turned on via an option to \digits?
I guess this is the wanted behavior for many users, so this should be 
made accessible easily... But maybe I'm wrong!

Best regards,
Morgan

ok, patched:

\def\digitpowerseparator
   {\ifx\collecteddigits\empty\else\cdot\fi10}

Dear all, I allow me to use this message for a related topic on the digits
command. I took a look at the "manual" on the digits command but did not
found a way to cut a number by group of three digits like
the numprint command, e.g. 1000000 becomes 1 000 000.
With the digits option 3, dots become thinmuskips. I would like to do
something similar but automatically for groups of three digits. For people
who know the numprint package, this is default option with the french
language.
Best regards.
Flavien.

Hi,

Does this feature exist now in ConTeXt?

TIA for any hints,
