Netscript Operators¶
Operators¶
Binary Operators¶
Binary operators require two operands and produce a result based on their values. In general, binary operators do not change the value of the operands.
Operator | Name | Example/Comments |
---|---|---|
= | Assignment | i = 5 would assign the value 5 to the variable i |
+ | Addition | 5 + 12 would return 17 |
- | Subtraction | 20 - 8 would return 12 |
* | Multiplication | 4 * 5 would return 20 |
/ | Division | 50 / 10 would return 5 |
% | Modulo | 50 % 9 would return 5 |
&& | Logical AND | true && false would return false |
|| | Logical OR | true || false would return true |
< | Less than | 4 < 5 would return true |
> | Greater than | 4 > 5 would return false |
<= | Less than or equal to | 5 <= 5 would return true |
>= | Greater than or equal to | 5 >= 4 would return true |
== | Equality | 1 == 1 would return true |
!= | Inequality | 4 != 5 would return true |
=== | Strict equality | 1 === "1" would return false |
!== | Strict inequality | 1 !== "1" would return true |
Unary Operators¶
Unary operators require only a single operand and produce a result based on their values. Some unary operators will change the value of their operands. For example:
i = 0;
++i;
Running the pre-increment unary operator (++) in the code above changes the value of the variable i.
Operator | Name | Example/comments |
---|---|---|
! | Logical NOT operator | !true would return false, and !false would return true. Does not change operand's value |
- | Negation | Negates a number. Only works for numerics. Does not change operand's value |
++ | Pre-increment | ++i or i++. WARNING: This only pre-increments, even if you put i++. Changes operand's value |
-- | Pre-decrement | --i or i--. WARNING: This only pre-decrements, even if you put i--. Changes operand's value |
