Multiply Variable
Multiply Variable node is designed to perform multiplication operations on a specified variable and store the result back in the same variable. This node is useful for scaling up values, applying factors, or performing compound calculations within your workflow.
Properties Panel
Field
Description
Required
Node name
true
Variable Name
The name of the variable whose value will be multiplied
true
Value
The value by which the variable will be multiplied
true
Usage
Specify the name of the variable whose value you want to multiply.
Enter the value (the value by which the variable will be multiplied).
Behaviour
The node will retrieve the current value of the specified variable.
It will then multiply this value by the provided multiplier.
The result of the multiplication will be stored back in the same variable, overwriting its previous value.
If the variable doesn't exist, it'll raise an error.
Returns
The node updates the value of the specified variable with the result of the multiplication. You can access this updated value using Magical Autocomplete (e.g., $.variables.<variable_name>
) in any node below this node.
Example
Let's say you want to apply a 20% increase to a price:
Set Variable name to
$.variables.product_price
Set Multiplier to
0.5
If it exists and product_price
was 10
, it will now be 5
.
Best Practices
Ensure that the variable you're dividing contains a numeric value to avoid type conversion errors.
Consider adding a check for division by zero before this node if there's any chance the divisor could be zero.
Ensure that the variable is initialised earlier
