You can combine different datamash invocations:

     $ seq 10 | datamash mean 1
     5.5
     $ seq 10 | datamash mean 1 | datamash round 1
     6

You could try something like --format='%.0f'.  This works for printf,
and the manual says:

    --format=FORMAT
        print numeric values with printf style floating-point FORMAT

Example with printf:

    $ printf '%f %.0f\n' 5.5 5.5
    5.500000 6

HTH,
Erik
