Get the paper on r.mapcalc fto to moon.cecer.army.mil.
Apart from having to multiply by 100 to get
integers, you can do it with r.mapcalc.

|Another r.median related question. Does any one have a program/script
|that can compute variance / standard deviation for all pixels within each
|region (regions are defined by another map layer). That is, a program
|that works like r.average and r.median(if it would run) but that describes
|the variation within the area.
