Operators
Descriptions of the operators you can find in Drizzle
Operators
Some operators have different meanings when used either
infix or prefix notation.For example, the
- operator when used in infix notation denotes subtraction (2 - 1 # == 1) whereas with prefix notation gives negation (-1 # == -1).The operator meanings in the lists below are
infix notation unless stated otherwise.Arithmetic
+- Addition (
infix)1 + 2 # == 3
- Unary plus (
prefix)+1
-- Subtraction (
infix)2 - 1 # == 1
- Unary minus (
prefix)-1
*- Multiplication
2 * 3 # == 6
/- Division
5 / 2 # == 2.5
//- Integer Division (convert to integer by dropping the floating point)
5 // 2 # == 2
%- Modulo (remainder of a division)
5 % 2 # == 1
Logic
==- Equality
1 == 1 # true
!=- Inequality
1 != 1 # false
is- Object equality
- While
==will check if two objects have the same value,iswill check if they are the exact same object (i.e. two variables reference the same object, etc.)true is true # true
not- Logical NOT
not false # true
and- Logical AND
true and 1 == 1 # true
or- Logical OR
true or false # true
<- Less Than
2 < 3 # true
- Class Inheritance
Dog < Animal
>- Greater Than
2 > 3 # false
<=- Less Than or Equal To
3 <= 3 # true
>=- Greater Than or Equal To
3 >= 3 # true
Other
=- Assignment
let x: int = 3
->- Return Type Identifier
def test() -> int = return 3
