DESCRIPTION¶
r.surf.random produces a raster map layer of uniform random deviates
whose range can be expressed by the user. It is essentialy 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.
