Operators
Arithmetic operators
| Operator | Meaning |
|---|---|
+ |
Addition |
- |
Subtraction |
* |
Multiplication |
/ |
Division |
// |
Integer division |
% |
Remainder |
** |
Exponentiation |
Examples:
let a = 10 + 5;
let b = 10 - 5;
let c = 10 * 5;
let d = 10 / 5;
let e = 10 // 3;
let f = 10 % 3;
let g = 2 ** 8;
/ produces a floating-point result.
// produces an integer quotient using the current interpreter’s integer
division behavior.
Comparison operators
| Operator | Meaning |
|---|---|
== |
Equal |
!= |
Not equal |
< |
Less than |
> |
Greater than |
<= |
Less than or equal |
>= |
Greater than or equal |
Comparison expressions produce a bool.
let x = 10;
let a = x == 10;
let b = x != 5;
let c = x > 3;
let d = x <= 20;
Unary operators
Unary operators operate on a single expression.
let x = -10;
Precedence
From lower to higher precedence:
comparison
↓
+ -
↓
* / % //
↓
**
↓
unary
↓
postfix (calls and indexing)
Parentheses can be used to explicitly control evaluation order.
let x = (2 + 3) * 4;
