Final answer:
Calculated fields are used in software applications to display results of expressions that automatically update when related values change, unlike input, output, or conditional fields which have different functionalities.
Step-by-step explanation:
Fields that display the results of an expression that is recalculated each time a value in the expression changes are known as calculated fields. Calculated fields are commonly used in various software applications like databases, spreadsheets, and form builders.
They are designed to automatically recompute and update information based on changes in other data fields, allowing for dynamic data management. Unlike input fields, which are for user entry, or output fields, which merely display values, or conditional fields, which may change visibility or options based on certain conditions, calculated fields specifically handle the dynamic calculation of values.
The fields that display the results of an expression that is recalculated each time a value in the expression changes are calculated fields. Calculated fields are used in databases or spreadsheet applications to perform mathematical calculations or apply formulas to existing data.
