<div bgcolor="#FFFFFF" text="#000099">Hi,<br>
<br>
I have floating raster layers which values I want to round to x decimal places. I wonder if there is an function that allows me to round raster values to values x decimal places? There is the option
<i>round()</i> in r.mapcalc, but that rounds the raster values to nearest integer. I can work with integer values, using e.g.,
<i>r.mapcalc "output = round(input * 1000)"</i>. But an option to round values would be more convenient. Any suggestion?<br>
