GRASS:~> r.what --help
input Name of existing raster map
cache Size of point cache
null Char string to represent no data cell
east_north Coordinates for query
so the *'s you are seeing represent null values.
using null=NaN or something might be more useful to you if you want to
export the data to Matlab, etc..
