What kinds of operator overloads does Delphi support?

Question

I wonder what sort of operator overloads are possible (and with what version of Delphi)? Thanks to Hallvard\'s great write-up on operator overloading, I know of :

Answer 1

Actually, I found the answer to this myself, but kept the question as I can imagine people will search for this information regularly on stackoverflow;

The official description on operator overloaders can be found here : http://docwiki.embarcadero.com/RADStudio/en/Operator_Overloading_(Delphi)

Mainly, the ones I was looking for are named:

• Equal, for '=' comparison : Equal(a: type; b: type) : Boolean;
• NotEqual, for '<>' comparison : NotEqual(a: type; b: type): Boolean;
• GreaterThan, for '>' comparison : GreaterThan(a: type; b: type) Boolean;
• GreaterThanOrEqual, for '>=' comparison : GreaterThanOrEqual(a: type; b: type): resultType;
• LessThan, for '<' comparison : LessThan(a: type; b: type): resultType;
• LessThanOrEqual, for '<=' comparison : LessThanOrEqual(a: type; b: type): resultType;
