r.surf.random produces a raster map layer of uniform random deviates whose range can be expressed by  the
       user.  It is essentially the same as r.surf.gauss, but uses a linear random number generator instead.  It
       uses the random number generator drand48() or rand(), depending on the user’s platform.

       # check result

       With the histogram tool the cell values versus count can be shown.
