What type of attribute is best to use for showing a value converted using the latest exchange rates in your app?

Using a calculated attribute is the best choice for showing a value converted using the latest exchange rates in your app because calculated attributes are specifically designed to store values that are derived from other attributes or data sources. In this scenario, the exchange rate may change frequently, and a calculated attribute can dynamically re-evaluate its value based on the most current exchange rates at runtime.

This ensures that whenever the exchange rates are updated, the calculated attribute reflects the latest conversion without requiring manual updates or additional data entry. It leverages underlying logic that can pull the latest rates and perform the conversion automatically, providing real-time accuracy.

Other attribute types, such as text, integer, and boolean, do not fit this use case effectively. A text attribute would simply store a string of text, which wouldn't perform calculations. An integer attribute would be limited to whole numbers, making it unsuitable for financial data that requires decimals or specific formatting common in currency conversions. A boolean attribute is designed to hold binary values (true or false) and would not be applicable for representing a numerical currency value, whether converted or not.
