## DESCRIPTION

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.

Histogram of map generated with r.surf.random

## EXAMPLE

    g.region -p n=228500 s=215000 w=630000 e=645000 res=10
    r.surf.random out=random min=0 max=100

    # check result
    r.univar random
