- = (equality)
  The equality operator (=) returns a boolean value indicating whether the value of the first argument is equal to (one of the values of) the second.
- <> (inequality)
  The inequality operator (<>) returns a boolean value indicating whether the value of the first argument is not equal to (any of the values in) the second.
- < (less than)
  The less than operator (<) returns a boolean value indicating whether the value of the first argument is less than the value of the second.
- <= (less than or equal to)

- & (logical and)
  The logical and operator (&) returns true if both arguments are true.

- ~ (logical not)
