I'm also having the problem with the space after a comma in decimal numbers (like discussed here: German language: use of comma in numbers)
and I wonder if I can use both the icomma-package (which seems to be quite old) AND siunitx together.
I'm not sure if that makes sense, but I have a large writing project (Ph. D. thesis) which already contains a lot of numbers.
With siunitx I'd have to use the \num[]{} command for each one of them and I would not dare to replace something like that automatically, so I'd have to check each single number - that's impossible at the moment.
So I'd like to at least have an automated solution for the numbers used in math mode and that should be icomma - right?
My only concern is, if both packages could create a conflict - is that possible?
\nummacro insiunitxwas never intended to replace simply using math mode. It's there for cases where you want more complex formatting or where you may need to alter formatting for a single source (such as switching between,and.for decimals depending on the country of publication). – Joseph Wright Nov 30 '11 at 09:28icommaandsiunitxpossible – MostlyHarmless Nov 30 '11 at 09:56
