<div>map with values integer and >=0. </div>
<div> r.mapcalc "Dem.new=if(Dem>=0,int(Dem),null())"</div>
<div> </div>
<div>As my original map have values positive and negative, as well as</div>
<div>it is fload, my question is if are there a way of I force my output</div>
<div>map accept only integers>=0. By the way, is there a way</div>
