Process Purpose

The Basic Arithmetic process is used to perform basic arithmetic operations with values within variables such as:

• Addition

• Subtraction

• Division

• Multiplication

• % Modulo (calculates the remainder after a division operation).

The result of any of these arithmetic operations is always stored in a variable.

Check the provided Basic Arithmetic examples at the end of the topic.

When you add a process, you are required to define its settings. This occurs in the process's properties window which is displayed automatically after having added the Basic Arithmetic process.

If any subsequent edition is required, double-click the process to open its properties window and enter the necessary modifications.

Proceed as follows:

Values & Operation
Value 1	Define the first value for the intended arithmetic operator. Enter it or click and select a variable with that value. See Variable Definition.
Operator	Select the arithmetic operator from the drop down list.
Value 2	Define the second value for the defined arithmetic operator. Either enter it or click and select a variable with that value.
Format Rules
Integer	Define the number of integer positions.
Decimal	Define the number of decimal positions.
Fill With	Select the character to fill the result from the drop-down list (“None”, “Zeroes” or “Blank”).
Add Sign	Select the sign to be included in the result from the drop-down list ("None", the default option; "+/-" or "- only").
Preview
Displays a default format preview according to the selected options. Click to edit/customize the formatted preview. Click again to view the edited format preview result.
Store Result into Variable
Variable	Click to select the variable that will receive the result value of the arithmetic operation. See To Select/Create a Variable.

If required, use the icon on the upper right corner of the properties window:

Use the icon to attach any relevant notes to this process. Click it and enter your notes in the resulting text box. These notes will be displayed in the corresponding "Actions" tab or "Process" window (in the "Notes" field) and in the "Developer Report".

After filling in the required options, click to conclude or to abort the operation.

The added process is displayed in the corresponding "Actions" tab or "Process" window.

Use the right-click in MCL-Designer's input boxes to access some related options as well as the general "Cut", "Copy"; "Paste"; "Search" actions (active/inactive according to the current context).

Ex: If you right-click the "Variable" input box (included in a "Conversion's" properties window), you are provided with general editing/search actions and other more specific options such as "Variable Select" (see "Variable Select") ;"Variable Insert" (see "Variable Insert")"Insert Special Character" (see To Insert Special Characters into a Control's Text Input Field) and "Localization Select" (see Localization List).

If you right-click another input box, it nay provide other possibilities.
