Hello, i use this code to sort a table`s rows by values from a column but it doesnt do what i want for example it should sort the rows like this:
0; 0.1;1;2;....9;10 but my code sort`s like this : 0;0.1;1;10;2;...9; So its there any other way to do this sorting right(the sort of rows must be ascending by values from a column) or can someone tell me where i messed up?

public static DataTable sort(DataTable dt)
      {


         dt.DefaultView.Sort="["+dt.Columns["Distanta Euclidiana"]+"] asc";

          return dt;
      }
