The raster file writer only currently supports formats for which GDAL has "creation" support, not "copy" . See https://www.gdal.org/formats_list.html - AAIGrid supports copies only. This should be fixable with moderate effort -- we could create a temporary dataset in a supported format (possibly even in memory for smaller rasters), and then use GDAL's createcopy to write the result. This would open up support for all raster drivers with copy but not create support, including AAigrid, and a whole lot of other useful formats too. > 2. > > As an alternative I can use the "Raster" --> "Extraction" --> "Clip raster by > extent".

I don't fully understand the issue here -- although the dialog is showing that many decimal places, it doesn't affect the output file if the extraneous digits are set to 0.
