cxviii

CXVIII is the Roman numeral representing the integer 118. It is formed by adding the values of C (100) and XVIII (18), giving 118. The notation uses additive principles here; there is no subtractive pair such as IV or XC involved in this number.

In the system of Roman numerals, CXVIII appears wherever counting or sequencing is rendered in Roman form, such as year notation on inscriptions or in historical documents and literature. It can denote the year 118 in the Common Era (118 CE) or be used to indicate the 118th item in an ordered list, chapter, or festival schedule.

In modern contexts, Roman numerals like CXVIII are often used for page titles, outlines, monarchs or popes when using regnal numbers, and in film or book subtitles as stylistic choices. While rarely used for everyday arithmetic, CXVIII remains a standard representation in typographic and historical settings.
