+
-
*
/
|
&
The calculation is made for + - * / in double format (15-digit accuracy) and for & | in UInt64
format.

AND operation
AND logic operation of specified and existing value (resetting bits).
Assignment without evaluation
Assignment without evaluation to the right of the operator. The value is transferred to the
controller as specified.
Everything to the right of "=" (e.g. a variable) is neither interpreted by the package nor pro‐
cessed.
