[Qgis-user] Nodata and raster calculator

[Nicolas Cadieux]

I also have been doing it manually. There should be an option in the Qgis calculator for that but I did not find it. 
 Hopefully, someone will both teach us something new if the option exists...

	Hello,
I am using QGIS 2.6.1 raster calculator to mask a curvature raster to exclude a range of values. I am following the instructions at 
http://docs.qgis.org/2.6/en/docs/user_manual/working_with_raster/raster_calculator.html and am getting the proper output. My question is: Is it possible to output the nodata value instead of 0 (which is what the result is in the example) for the excluded values?
I am using floating point rasters which default to a 3.whatever e-38 nodata value which means that I have to change the nodata manually after to 0 (which sometimes causes additional problems with borders, etc.)
I may also be doing this completely wrong, strong possibility.
