The built-in scripting language supports the
following logic and arithmetic operators.
Logic operators
|
Operator |
Usage |
Description |
| AND
|
A AND B
|
TRUE if A and
B are both TRUE |
| OR
|
A OR B
|
TRUE if A is
TRUE, or B is TRUE, or both |
| XOR
|
A XOR B
|
TRUE if A is
TRUE, or B is TRUE, but not both |
| NOT
|
NOT A
|
TRUE if A is
FALSE |
| =
|
X = Y
|
TRUE if X is
equal to Y |
| >
|
X > Y
|
TRUE if X is
greater than Y |
| >=
|
X >= Y
|
TRUE if X is
greater than or equal to Y |
| <
|
X < Y
|
TRUE if X is
less than Y |
| <=
|
X <= Y
|
TRUE if X is
less than or equal to Y |
| <>
|
X <> Y
|
TRUE if X is
not equal to Y |
| &
|
X & Y
|
Bitwise AND:
0101 (decimal 5)
AND 0011 (decimal 3)
= 0001 (decimal 1)
|
| |
|
X | Y
|
Bitwise OR:
0101 (decimal 5)
OR 0011 (decimal 3)
= 0111 (decimal 7)
|
| ^
|
X ^ Y
|
Bitwise XOR:
0101 (decimal 5)
XOR 0011 (decimal 3)
= 0110 (decimal 6)
|
| ~
|
~ X
|
Bitwise NOT:
NOT 0101 (decimal 5)
= 1010 (decimal 10)
|
| >> n
|
X >> Y
|
Rotate
n
bits to right:
0110 (decimal 6) ROTATE RIGHT
= 0011 (decimal 3)
|
| << n
|
X << Y
|
Rotate
n
bits to left:
0110 (decimal 6) ROTATE LEFT
= 1100 (decimal 12)
|

Loop functions.
Arithmetic operators
|
Operator |
Usage |
Description |
| +
|
X + Y
|
Add
(plus) |
| -
|
X - Y
|
Subtract
(minus) |
| *
|
X * Y
|
Multiply
by |
| /
|
X / Y
|
Divide
by |
Arithemtic operators are resolved from left to right
according to the standard order of evaluation. To change the order,
enclose in parentheses the part of the equation to be resolved
first. For example, the following equation produces a result of 11
because multiplication is evaluated before addition; the equation
multiplies 2 by 3 and then adds 5 to the result:
5+2*3
In contrast, if you use parentheses to change the syntax, 5 and 2
are added together and then multiplied by 3 to produce 21:
(5+2)*3
