the German decimal separator is ",". So pi will be
represented by "3,1415" rather than "3.1415". As far as I
know this behaviour is controlled by the LC_NUMERIC
environment variable.

Now, I notice the following on my system: When I'm in editor
Vim I may say in command mode:

  :ruby puts 4.56
  :!ruby -e 'puts 4.56'

The former is the built-in ruby interface, the latter a call
to a child process and will show thats standard output.

But I happen to encounter two different results. The
built-in version gives "4,56"; the child process prints
"4.56".

How can I make the normal Ruby process print a comma, too?

Thanks in advance

I'm sorry but LC_NUMERIC is disabled at the current level of
implementation, since it causes more headache than merit, e.g. causing
marshal incompatibility, syntax error, etc.  We will support it in the
future.  But not in specific near future.
