Operator Precedence

Highest precedence first:

Order	Operators	Grouping
1	Calls f(...), indexing x[i], and field access x.field	Left to right
2	Unary operators, including -, not, and length	Right to left
3	*, /, //, %	Left to right
4	+, -	Left to right
5	<, <=, >, >=	Left to right
6	&	Right to left
7	in, not in, ==, !=	Left to right
8	and	Left to right
9	or	Left to right

Reporters
