Errata Entry Question
In the Errata there is a posting for pages 76 & 77 Error in Code that states, "Last line should be MessageBox.Show(dblArea.ToString, "Area").
dblArea is declared as Double. Why is it necessary to convert it to a string? The program runs with, or without, the addition of "ToString".
Is there ever a time when one would want to convert a Double to a String? If so, when?
