Hi Les,
You can add a "create option" for your conversion:
name: DECIMAL_PRECISION
value: 3
to round the values in your output.
QGIS uses the GDAL software for the conversions, and those options can
be found in the GDAL documentations:
https://gdal.org/drivers/raster/aaigrid.html
There's a "batch" option in the raster conversion dialog, which I have
never used (cause I would write a script) but I hope you figure out how
it works. :)
Good luck,
Raymond

For a project I’m working on I need to translate a collection of terrain
tiles from .adf to .asc format. When I look at the source data the
height values are at most to 3 decimal places (millimetres effectively).
After translation to .asc format, all the height values have 17(!)
decimal places.
I’m assuming there’s a conversion going on, but is there a way to
specify the output accuracy?
Also, is it possible to batch convert a number of files, rather than
loading and converting each one individually?
Many thanks for any tips,
Les Neilson
