Yes, I used that (also with the SODA maps).

You are confusing at time the precision CELL (= integer) and "cell"
(historically used for "raster" maps as opposed to "vector" map:
http://grass.osgeo.org/programming7/gislib_cmdline_parsing.html#gisprompt_Member

"new,cell,raster"   G_open_new("cell", "map")
"old,vector,vector" G_open_old("vector", "map")

... this cell is not related to precision but means raster map which
can well be a floating point map.
