Comparision operators

[Neelke]

I've known how these comparision operators work for a couple of weeks and I've not found out what all of them does. I know these:

== Equal to
< Less than
> Greater than
//= Less than/Greater than or equal to
!= Not equal to
&& And
|| Or
! Not

Can someone mention the others? (If there now are more). Just to be secure.
