Delphi variable problem

Hello, I would like to use integer value for an example 2500 000 000, Delphi gives following error : it says [Error] [login to view URL](5210): Overflow in conversion or arithmetic operation When using 2000 000 000 then there is not any problem. Using longint won't help, I have tested. Also int64 gives errors, test it on your Delphi 7 first. What could be wrong? I can give more details if you need, just ask.
