Thanks. I tried:
$ locale -k LC_NUMERIC | grep decimal_point | sed 's/[^\.,]//g'
,
$

Works fine.

I don't need the thousands separator in this case, since I was only going
to use it for bc, which doesn't seem to use them.
I just want to use the decimal character on my numerical keypad when typing
the numbers to my script, and I just thought that it would be nice if the
simple script also works on a different setup.

So now I just let the user (me) type in the systems decimal separator, and
the script replace it with a decimal point, There some calculation, and the
answer has i decimal point that needs to be converted to the system's
decimal separator for output.

Thanks! Now I'm just going to make the script work as well…
