<p><font size="-1">Hello all,</font></p>
<p><font size="-1">I've done a sum with r.series from 8 rasters
previously calculated with r.mapcalc. Each raster cell content
is 0 or 1. So the sum raster cells should have 0 to 8. I was
looking at r.category to set labels like "1 to 2", "3 to 4",
etc. To see my raster values, I've done a r.describe, and the
result surprised me :<br>

...<br>

<p><font size="-1">If I do int(value) with r.mapcalc in my first
raster (value is integer), r.describe returns integer result as
expected.<br>
</font></p>
<p><font size="-1">Why r.describe return float values ? how they are
calculated ? why I must make a int() on a integer to get an
integer ?<br>
</font></p>
<p><font size="-1">Since my values are integer, how can I force
raster in CELL instead of DCELL ?</font></p>
<p><font size="-1">Thanks to help me to understand this !</font></p>
<p><font size="-1">Regards,</font></p>
