Math execute
Math execute is an action used to perform basic arithmetic operations (such as addition +, subtraction -, multiplication *, division /) or complex mathematical expressions from available variables, and then store the result in an output variable.
Expression: The content of the arithmetic calculation to be performed. You can combine specific numbers and available variables (For example: (5 + 3) * 2 or $price * $quantity).
Output variable: The name of the variable to store the result after the calculation is complete.
Practical example 1: Calculate the total order amount (Multiply and Add)
Suppose you are creating a script for automatic purchasing or scraping order data. You have a product quantity variable as $quantity = 3, a unit price variable as $price = 150000, and a fixed shipping fee of 30000.
Configuration:
Expression: Enter the expression ($price * $quantity) + 30000
Output variable: Enter the variable name to store the result as $totalAmount.
Result: The system will calculate the value as 480000 and assign it to the variable $totalAmount.
