Expressions

Expressions are only permitted between parameters of basic types. An expression could be:

• A value of basic type.
• A data access.
• A list aggregation operation.
• An operation between one or more expressions. In the following table we can find all implemented operators with their associativity and types. They are sorted according to their priority:

Operator	Associativity	Input type	Output type
not	-	bool	bool
/, %, *	Left	int	int
+, -	Left	int	int
<, <=, >, >=	Left	int	bool
==, !=	Left	int or bool	bool
and, or	Left	bool	bool
if-then-else	Right	int or bool	int or bool

if-then-else structure

<bool_expr> ? <expr1> : <expr2>

If <bool_expr> evaluates true resolves <expr1> else <expr2>.
