Results may be approximate.” Effective data source handling ensures calculations are conducted with the best available, verified data.
-
Calculation Errors
Calculation errors, such as division by zero, necessitate robust error trapping mechanisms. The system must intercept calculation failures and provide useful diagnostics instead of crashing. Example: If the exchange rate is zero, attempting to divide the source amount results in an error. The system should display a notification: “Error: Cannot perform calculation due to a zero exchange rate.” Prevention of silent failures improves confidence.
-
Unexpected System Events
Unexpected system events, such as network interruptions or database access failures, must be managed gracefully. The system should avoid data corruption and present informative messages. Example: If a network interruption occurs during the exchange rate retrieval, the system must display a message: “Network error: Unable to retrieve exchange rate. Please try again later.” These system events do not compromise the data.
A well-structured approach to error handling enhances the reliability and trustworthiness of currency translation. Robust handling mitigates risks, offering confidence in the reported results and promoting wider use of the service.
