   Drainage map should be INT, there is no reason for it to be FP
   because the program uses D8 algorithm, there are only 8 directions
   of flow. only L and S factor could be output as FP (here they are 
   multiplied by 100) but I am not sure whether it is worth the effort
   because they are not very good anyway.
