Didn't work, but thanks.
Here's my test script.
DECLARE @i DECIMAL(5, 3) = 0;
DECLARE @Inc DECIMAL(3, 2) = 0.01;
WHILE @i < 2
PRINT CONCAT(@i, ', ', ROUND(@i + 0.3, 0, 1));
SET @i = @i + @Inc;
Now please show me yours.
If the answer to your question can be found with a brief Google search, please perform the search yourself, rather than expecting one of the SSC members to do it for you.
