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. |
