Here is how I deal with this problem in my program :

use POSIX qw/locale_h/;

# code that don't care what the decimal separator is
setlocale(LC_NUMERIC, 'C');
# code that needs the decimal separator to be '.'
setlocale(LC_NUMERIC, '');
# code that don't care what the decimal separator is

Let me know if there is a better way.
