Operators

Arithmetic operators

Operator	Description	Complexity
+	Addition	1 for Int 1 for BigInt in Standard library version 8 8 for BigInt in Standard library version 7 and 6 1 for String 2 for ByteVector
-	Subtraction	1 for Int 1 for BigInt in Standard library version 8 8 for BigInt in Standard library version 7 and 6
*	Multiplication	1 for Int 1 for BigInt in Standard library version 8 64 for BigInt in Standard library version 7 and 6
/	Division	1 for Int 1 for BigInt in Standard library version 8 64 for BigInt in Standard library version 7 and 6
%	Remainder	1 for Int 1 for BigInt in Standard library version 8 64 for BigInt in Standard library version 7 and 6
-	Unary minus	1 for Int 1 for BigInt in Standard library version 8 8 for BigInt in Standard library version 7 and 6

Please note:

• The / operator uses the FLOOR rounding method, see Rounding variables. For example, the result of -1 / 100 is -1.

• Minus with a space after it is always considered a binary operator. For example, the code

  let b = 100
  - 100
  

  defines the variable b and sets its to 0.

  Minus placed at the beginning of a line or element with no space after it is considered a unary operator. For example, the code

  let b = 100
  -100
  

  is an expression whose value is -100.

Comparison operators

Operator	Description	Complexity
<	Less than	1 for Int 1 for BigInt in Standard library version 8 8 for BigInt in Standard library version 7 and 6
>	Greater than	1 for Int 1 for BigInt in Standard library version 8 8 for BigInt in Standard library version 7 and 6
<=	Less than or equal	1 for Int 1 for BigInt in Standard library version 8 8 for BigInt in Standard library version 7 and 6
>=	Greater than or equal	1 for Int 1 for BigInt in Standard library version 8 8 for BigInt in Standard library version 7 and 6
==	Equality	1
!=	Inequality	1

Local definition operators

Operator	Description	Complexity
func	Function local definition	0*
let	Lazy definition of a variable	0
strict	Strict definition of a variable	1 or 2*

* Any function call has a complexity of at least 1. See the Complexity article for more information.
** See the Variables article for more information.

Conditional operators

Operator	Description	Complexity
if ... then ... else	Conditional statement	0*
match ... case	Pattern matching	Number of case

* See the Complexity article for more information.

List operators

Operator	Description	Complexity
++	Concatenation	4
:+	Adding the element to the end of the list	1
::	Adding the element to the beginning of the list	1

See examples in the List article.

Logical operators

Operator	Description	Complexity
&&	Logical AND	0
||	Logical OR	0
!	Logical negation	1

Please note: logical operators only work with values of Boolean type. Int values are not supported.
