Can one set the Raster Value Export precision to ArcGIS /Info ASCII (Decimal points)?

Andrew Swanepoel
I have produce a rasterised spatial multi criteria map using ILWIS and wish to export this to an ArcGIS compatible format Arc/Info ASCII.ASC using the export tool. ILWIS displays to the second decimal point, however when I export this to Arc/Info ASCII.ASC format the resultant file only exports to a single decimal point. Is there a way to set the export precision? When I import the Arc/Info ASCII.ASC file to ArcGIS it only shows a single decimal point.

ArcMap (I have 10.3) support ILWIS files out of the box (using GDAL); in ArcCatalog look for the mpr files.
This way you don't have to care about precision loss during export.
BTW for exports consider using another binary format instead of ASCII, such as ERDAS imagine, because usually the precision is not changed
