Order of Precedence

Order of operations, also called operator precedence, is a set of rules specifying which procedures should be performed first in a mathematical expression.

Precedence Overview

ⓘ

• Highest precedence means highest priority
• Associativity is (then) done from left to right, for example 3 + 5 + 8 will be processed as ((3 + 5) + 8)

Precedence	Type of Operator	Examples
11	Nular operators (commands with no arguments): commandName	Variables Values () / [] / {} / "" / '' -enclosed expressions
10	Unary operators (commands with 1 argument): commandName a	+a -a +array ! b not b
9	Hash-select operator	array # index
8	Power operator	a ^ b
7	Number multiplication, division and remainder atan2 Config access (/)	a * b a / b a % b a mod b a / b a atan2 b
6	Number addition and subtraction Array addition and subtraction String addition min and max commands	a + b a - b arr1 + arr2 arr1 - arr2 str1 + str2 a min b a max b
5	else (if-then-else structure)	N/A
4	Binary operators (commands with 2 arguments): a commandName b	setDir switch colon (:)
3	== and != comparisons Number comparisons Config access (>>)	a == b a != b a > b a < b a >= b a <= b config >> name
2	Logical and operator	&& and
1	Logical or operator	|| or

Examples

Input	Process	Comment
1 + 2 * 3	1 + (2 * 3)	result equals 7, and not 9 (see also PEMDAS)
sleep 10 + random 20	(sleep 10) + random 20	sleep 10 will return Nothing, then + random 20 will be calculated but not used. sleep (10 + random 20) should be used instead
