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:

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.
