Operator overloading is a very nice feature of the Delphi language.
However. the Delphi documentation on Operator overloading is not completely right.
Below is my table of what I found out so far, and some notes.
It is part of my “Nullable types in Delphi” session that I gave on some conferences.
The downloads for that session contain more detailed information.
This is just an abstract to get you going and a try to answer this operator overloading question on Stackoverflow.
Download the full presentation to get more in depth information.
Let me know if you need more information.

Edit 20140822 since originally posting, JEDI moved to a GIT repository, so I changed some URLs and added that it is up to date until Delphi XE7.
Finding the correct VERxxx conditional define for a particular Delphi version is asked by a lot of people.
Even the first link in the above search, does not contain the full list!
But: JCL comes to the rescue
The JCL file JEDI.INC usually (read: like 99.999% of the time) is up to that with that information soon.
Currently, it contains all the defines starting with Delphi 1, up to Delphi 2010 XE7.
You can always browse the to JEDI.INC with this link to the sourceforge trunk. link to the GitHub master version.
In fact that file contains a lot more useful defines.
Actually, having the JCL and/or JVCL at hand is a very good practice: it is filled with high quality code that solves a lot of everyday problems.
Note:
VER190 (by some people attributed to the wrong Delphi version) is only used by Delphi 2007 for .NET (Delphi 2007 for Win32 used VER185 by itself and shares VER180 with Delphi 2006 for Win32).
The number 13 (in between Delphi 2009 aka Delphi 12, and Delphi 2010 aka Delphi 14) was never used as a Delphi version number
Since Delphi is mainly developed in the USA, and since a lot people there have Triskaidekaphobia, they showed mercy to those and skipped Delphi 13.
