Operators
General
Operator | Description |
---|
Type | Get the ProcessTypeID of a ProcessType or define a new datatype. See Type. |
. (period) | Element access: <struct>.<element> . In case of a struct array, if no arrayelement is specified, it points to [0] (see example). |
Maths
Operator | Description |
---|
+ | Addition. |
- | Deduction |
* | Multiplication. |
/ | Division. |
% | Modulus (remainder). |
Logic
Operator | Description |
---|
|| | OR. One or the other or both. |
&& | AND. Both. |
^^ | XOR. One or the other, but not both. |
! | NOT. |
Bitwise
(Logical operation per bit.)
Operator | Description |
---|
| | BOR. One or the other or both. |
& | BAND. Both. |
^ | BXOR. One or the other, but not both. |
~ | BNOT. |
<< | Bitshift left, causes bits to move left a certain number of positions. |
>> | Bitshift left, causes bits to move right a certain number of positions. |
Memory
Operator | Description |
---|
& | OFFSET. Get the memory address of a variable. See pointer . |
* | POINTER. Get access to the variable a pointer is pointing to. See pointer . |
