Arithmetic operators
Arithmetic operators are used to perform numeric calculations. The operators available are the following:
- Addition:
+ - Subtraction:
- - Multiplication:
* - Division:
/ - Modulus:
% - Shift left:
-shl - Shift right:
-shr
As well as numeric calculations, the addition operator may also be used with strings, arrays, and hashtables; the multiplication operator may also be used with strings and arrays.
Operator precedence
Mathematical operations are executed in a specific order. For example, consider the following two simple calculations:
3 + 2 * 2 2 * 2 + 3
The result of both of the preceding expressions is 7 (2 multiplied by 2, then add 3).
PowerShell, and most other programming languages, will calculate elements of an expression using multiplication (*), division (/), and modulus (%) first. Addition (+) and subtraction (-) are calculated next.
PowerShell has two additional operators in this category, -shl and -shr. These two have the lowest precedence and are only executed once all other operations...
