I don't understand the solution given above, because it does not work for me.
Sure %.; will switch the decimal seperator to period, this still does not mean that it will skip over the "," when reading 1,450. It will still read only the 1 because anything that is not part of a decimal string will terminate the number field.
I would just do a global replace of all commas with nothing and then convert to an array. (LV 8.0). Now %f will work just fine.
