Which type of variable is typically used to store the results of a decision point in a flow?

A Boolean variable is used to store the results of a decision point in a flow because it can represent two possible outcomes: true or false. In many automation tasks, particularly those designed in UiPath, decision points are crucial for controlling the flow of execution based on specific conditions.

When a decision point evaluates an expression or condition, the outcome determines which path the workflow will follow next. Since a Boolean variable can effectively capture these two states, it is ideal for this purpose. For example, if the condition checks whether a certain value is greater than another, the Boolean variable will hold true if the condition is met and false if it is not, guiding subsequent actions in the automation process.

In contrast, other variable types like integer, string, or array do not directly serve the purpose of representing binary outcomes from decision-making processes. Integers might store numerical values, strings handle textual data, and arrays are used to store lists of values, which are not suited for simple true/false evaluations common to decision points. Thus, the Boolean variable is the most appropriate choice for handling the results of decision points in a flow.
