Natural

The names of the product elements.

The name of the type.

A mapping of Roman numeral symbols (represented as strings) to their corresponding Natural values.

This map is constructed using the romanValues sequence, which contains tuples of Roman numeral strings and their associated Natural values. The additional entry ("", Zero) is appended to ensure a mapping for the empty string to the Zero natural number.

Roman numeral keys in this map adhere to the conventional Roman numeral format (e.g., "I", "V", "X").

The map can be used for parsing or validating Roman numeral strings by retrieving the Natural value associated with a particular Roman numeral key.

A list of tuples associating Roman numeral symbols with their corresponding Natural values. NOTE: this list must not change its order since it is used in toString.

The Roman numeral system is represented as pairs of strings (symbols) and their Natural value equivalents. The list is structured to facilitate conversion between Roman numerals and natural numbers.

Roman numeral symbols included:

• "M" represents 1000 (Thousand)
• "CM" represents 900 (NineHundred)
• "D" represents 500 (FiveHundred)
• "CD" represents 400 (FourHundred)
• "C" represents 100 (Hundred)
• "XC" represents 90 (Ninety)
• "L" represents 50 (Fifty)
• "XL" represents 40 (Forty)
• "X" represents 10 (Ten)
• "IX" represents 9 (Nine)
• "V" represents 5 (Five)
• "IV" represents 4 (Four)
• "I" represents 1 (One)
