Do you have some kind of locale problem going on?

Your data file seems to use period as the decimal
separator and but at least your printf writes out
comma as separator. This might be sufficient to cause
your problems. (check the return value from fscanf in
order to see how many values it recognized)


some thing like setting your locale to C might
fix the problem.
