Introduction
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
Precedence | Type of Operator | Examples |
---|---|---|
11 |
Nular operators (commands with no arguments):
|
|
10 |
Unary operators (commands with 1 argument):
|
|
9 | Hash-select operator | |
8 | Power operator | |
7 | ||
6 | ||
5 | N/A | |
4 |
Binary operators (commands with 2 arguments):
|
|
3 | ||
2 | Logical and operator | |
1 | Logical or operator |
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. |
