CREATE FUNCTION dbo.trim0(@val numeric(18,7))
    RETURNS VARCHAR(20)
AS
BEGIN
  RETURN   
  CASE 
    WHEN CAST(@val AS INT)=@val THEN LTRIM(CAST(@val AS INT)) 
    ELSE LEFT(@val,LEN(@val)-PATINDEX('%[^0]%.%',REVERSE(@val))+1)
  END
END
GO

drop table test

select dbo.trim0(col1) as col1,dbo.trim0(col2) as col2,dbo.trim0(col3) as col3
from test
