Címletfájl

Címletfájl, a Hungarian term, translates to "denomination file" or "value file" in English. This type of file is commonly used in software applications, particularly those dealing with financial transactions, currency exchange, or any system that requires managing distinct units of value.

The primary purpose of a címletfájl is to store and define the available denominations or units that a system recognizes. For instance, in a point-of-sale system, a címletfájl might list the different banknotes and coins of a particular currency (e.g., $1, $5, $10, $20, $0.25, $0.50). In a cryptocurrency wallet, it could define the smallest divisible units of a coin.

These files often contain structured data, typically in formats like CSV, JSON, or XML. Each entry in the file usually includes a unique identifier for the denomination, its human-readable name, and its numerical value. This structured approach allows software to easily parse and utilize the information.

Using a címletfájl offers several advantages. It centralizes the definition of denominations, making it easier to update or modify them without altering the core application logic. This is crucial for systems that need to adapt to new currency releases or changes in monetary policy. Furthermore, it promotes consistency across the application by ensuring that all parts of the system refer to the same set of defined values. This can help prevent errors related to incorrect denomination representation or calculation.
