  #1896001

  I did test as well.

  CREATE TABLE #Test(

  Units decimal(10,5),

  DesiredResult decimal(10,5),

  );

  INSERT INTO #Test SELECT

  0.3, 0.3 UNION ALL SELECT

  0.1, 0.1 UNION ALL SELECT

  1.4, 1.4 UNION ALL SELECT

  1.5, 2 UNION ALL SELECT

  1.7, 2 UNION ALL SELECT

  0.8, 1 UNION ALL SELECT

  0.49, 0.49;

  SELECT *,

  CASE WHEN ROUND(Units,0) = ROUND(Units,0,1)

  THEN Units ELSE ROUND(Units,0)

  END,

  case when (units - floor(units)) < 0.49 then round(units,2)

  when (units - floor(units)) > = 0.50 then round(units,0)

  end

  FROM #Test

  GO

  DROP TABLE #Test
