Operators
Operators in Flexa are special symbols or keywords used to perform operations on values and variables. They are categorized by their functionality, such as arithmetic, logical, or assignment operations.
This page provides a concise reference to all operators available in the Flexa language.
Arithmetic Operators
These operators perform basic mathematical operations:
| Operator | Description |
|---|---|
+ |
Addition |
- |
Subtraction |
* |
Multiplication |
/ |
Division |
% |
Modulo (remainder) |
** |
Exponentiation (power) |
/% |
Floor division (integer result) |
Comparison Operators
Used to compare values. These expressions return a boolean result:
| Operator | Description |
|---|---|
== |
Equal |
!= |
Not equal |
< |
Less than |
> |
Greater than |
<= |
Less than or equal |
>= |
Greater than or equal |
<=> |
Three-way comparison. Returns: • -1 if left < right• 0 if equal• 1 if left > right |
Logical Operators
Used for boolean logic:
| Operator | Description |
|---|---|
and |
Logical AND |
or |
Logical OR |
not |
Logical NOT |
Bitwise Operators
Operate directly on binary representations of integers:
| Operator | Description |
|---|---|
& |
Bitwise AND |
\| |
Bitwise OR |
^ |
Bitwise XOR |
~ |
Bitwise NOT |
<< |
Left shift |
>> |
Right shift |
Assignment Operators
Used to assign values to variables:
| Operator | Description |
|---|---|
= |
Simple assignment |
+= |
Add and assign |
-= |
Subtract and assign |
*= |
Multiply and assign |
/= |
Divide and assign |
%= |
Modulo and assign |
/%= |
Floor division and assign |
**= |
Power and assign |
&= |
Bitwise AND and assign |
\|= |
Bitwise OR and assign |
^= |
Bitwise XOR and assign |
<<= |
Left shift and assign |
>>= |
Right shift and assign |
Increment and Decrement
Shorthand for increasing or decreasing a value:
| Operator | Description |
|---|---|
++ |
Increment by 1 |
-- |
Decrement by 1 |
Value Reference Operators
Used for referencing and dereferencing variables:
| Operator | Description |
|---|---|
ref |
Get the original reference of a value |
unref |
Get a copy of a value |
Note: struct type values are referenced by default.
Type and Introspection Operators
Useful for inspecting or identifying values at runtime:
| Operator | Description |
|---|---|
typeof(x) |
Returns the type name of x as a string e.g. "int", "bool", "string", "MyStruct" |
typeid(x) |
Returns a unique integer ID for the type of x |
refid(x) |
Returns the reference ID of an object or array (useful to check if two references point to the same entity) |
is_struct(x) |
Returns true if x is a struct instance |
is_array(x) |
Returns true if x is an array |
is_any(x) |
Returns true if x is of type any |
Ternary Operator
Shorthand conditional expression:
condition ? expression_if_true : expression_if_false
Example:
var result = age >= 18 ? "adult" : "minor";
