As you just saw in the variables section, assignment operators are necessary to fill variables with values and make calculations and changes to them:
|
Operator |
Meaning |
Description |
|
= |
Assign |
Assigns the value on the right to the left one. |
|
+= |
Add and assign |
Adds the right value to the left one and assigns it. |
|
-= |
Subtract and assign |
Subtracts the right value from the left one and assigns it. |
|
*= |
Multiply and assign |
Multiplies the right value by the left one and assigns it. |
|
/= |
Divide and assign |
Divides the right value by the left one and assigns it. |
|
%= |
Modulo and assign |
Invokes a modulo between the right value and the left one and assigns it. |
Some examples are as follows:
#region assignment operators with numeric values
#initial assignment
$numericValue = 123 # 123
# $NumericValue = $NumericValue + 877
# $NumericValue = 123 + 877
$numericValue += 877 # 1000
# $NumericValue = $NumericValue - 500
# $NumericValue = 1000 - 500
$numericValue -= 500 # 500
# $NumericValue = $NumericValue * 2
# $NumericValue = 500 * 2
$numericValue *= 2 # 1000
# $NumericValue = $NumericValue / 10
# $NumericValue = 1000 / 10
$numericValue /= 10 # 100
# $NumericValue = $NumericValue % 3
# $NumericValue = 100 % 3
$numericValue %= 3 # 1

#region assignment operators with strings
#initial assignment

# $stringValue = 1000 / 10
$stringValue /= "this" # ERROR
# $stringValue = $stringValue % 3
# $stringValue = 100 % 3
$stringValue %= "Val" #ERROR
