Converting Integer value into AnsiString in Delphi 2009

Question

IntToStr() function returns string which is Unicode now. I want to convert to AnsiString. Can I use AnsiString(IntToStr(I)) safely?

Answer 1

Sure. Or you can use IntToAnsiString (written by Dr. Bob):

function IntToAnsiStr(X: Integer; Width: Integer = 0): AnsiString;
begin
   Str(X: Width, Result);
end;

Answer 2

Yes, you can safely convert the UnicodeString returned by IntToStr to an AnsiString. The reason it's safe is that the string it returns will only contain the digit characters '0' through '9', not any fancy Unicode digits, so the conversion to AnsiString will not lose any information.
