Evaluate

This is a pre-built Action located under the @Generic Element. The functionality of this Action in Avo Assure is to execute a mathematical operation based on the provided value. The execution result is stored in the dynamic variable.

Syntax

Input Value: <operand1> <operator> <operand2>

Note: If your expression is long or complicated, provide the values inside parentheses () so the system can read it correctly. For example: (74-836)/(738+29).

Argument	Description
<operand1> (Required)	Provide the first operand (value or variable) to use in the calculation.
<operator> (Required)	Provide the operator for the calculation. Supported operators are: + (Addition) - (Subtraction) * (Multiplication) / (Division) ^ (Exponentiation)
<operand2> (Required)	Provide the second operand (value or variable) to use in the calculation.

Output Value: <Dynamic Variable>;<Dynamic Variable>(Optional)

Argument	Description
<Dynamic Variable> (Required)	This dynamic variable stores the evaluated mathematical result.
<Dynamic Variable> (Optional)	This dynamic variable stores the status as True or False.

Example 1: Performing Addition Using Two Numeric Values

In this example, we explain how to perform an arithmetic operation using two numbers.

• Action: Evaluate

• Input Value: 235+399

  • The first argument (235) specifies the first number.

  • The second argument (+) specifies the addition operator.

  • The third argument (399) specifies the number added to it.

• Output Value: {Value}

  • The calculated value (634) is stored in this {Value} dynamic variable.

  • If a second output variable is provided, the action returns the status as True or False:

    • True: If the operation executes successfully.

    • False: If the operation fails due to invalid input or unsupported format.

Logical Explanation: The Evaluate action fetches the value from the Input Value column (235+399). It adds both values and stores the result (634) in the {Value} variable.

Example 2: Adding Two Variables Containing Numeric Values

In this example, we explain how to perform an arithmetic operation using two variables.

• Action: Evaluate

• Input Value: {Price1}+{Price2}

  • The first argument ({Price1}) specifies the value (784) stored in the variable.

  • The second argument (+) specifies the addition operator between the values which is stored in the variables.

  • The third argument ({Price2}) specifies the value (988) stored in the variable.

Note: Before performing this operation, two dynamic variables must be created to store values for {Price1} and {Price2}. After creating them, the Evaluate action is used to add their values.

• Output Value: {TotalPrice}

  • The calculated value (1772) is stored in this {TotalPrice} dynamic variable.

  • If a second output variable is provided, the action returns the status as True or False:

    • True: If the arithmetic operation executes successfully.

    • False: If the operation fails due to missing or non-numeric variable values.

• Logical Explanation: The Evaluate action fetches the values from the Input Value column ({Price1}+{Price2}). It adds their numeric values (784+988) and stores the result (1772) in the {TotalPrice} variable.

Example 3: Performing a Complex Arithmetic Expression Using Parentheses

In this example, we explain how to perform an arithmetic operation using a longer expression that requires parentheses for correct evaluation.

• Action: Evaluate

• Input Value: (10+5)*(94+26)

  • The first argument ((10+5)) groups the addition so the system processes it before multiplication.

  • The second argument (*) specifies the multiplication operator that combines the results of both grouped expressions.

  • The third argument ((94+26)) groups another addition expression that will be multiplied with the first result.

• Output Value: {Value}

  • The final calculated value (1800) is stored in this {Value} dynamic variable.

  • If a second output variable is provided, the action returns the status as True or False:

    • True: If the arithmetic operation executes successfully.

    • False: If the operation fails due to an invalid expression or undefined variable.

• Logical Explanation: The Evaluate action fetches the value from the Input Value column ((10+5)*(94+26)). Because both expressions are enclosed in parentheses, the system first adds 10 + 5 = 15. It then adds 94 + 26 = 120. The system multiplies 15 × 120, producing the result 1800, which is stored in the {Value} variable.
