CCCXL

CCCXL is the Roman numeral representation of the integer 340. In the standard Roman numeral system, the symbols C (100) and XL (40) are combined to form 300 + 40. The notation follows the subtractive principle for the 40 combination, where X (10) precedes L (50). This style of numeral has been used historically in various contexts, such as numbering centuries, legal documents, and sports event titles.

The numeral appears on European road signs and route markers that number highways using Roman numerals; for example, a road labeled CCCXL would be the 340th route in that numbering scheme. It is also used in the titling of books or chapters, where a volume might be titled “History of Europe: Volume CCCXL” to denote the 340th volume in a series.

In computative and cataloguing systems, the string CCCXL can serve as a catalog number or a model identifier. For instance, some machinery and equipment models use a Roman numeral suffix to indicate a particular version or edition, and CCCXL might denote the 340th iteration.

The literacy of Roman numerals is taught in many education systems, and the number 340 is sometimes used as an example in lessons illustrating subtractive notation, numeral placement, and the combination of multiples. The symbol CCCXL remains a concise way to represent a specific large integer across technical and historical documentation.
