DXLII

DXLII is the Roman numeral representation of the number 542. In Roman numerals, D equals 500, XL equals 40, and II equals 2, so DXLII denotes 500 + 40 + 2 = 542. The form reflects the subtractive principle used in Roman numerals, where smaller values placed before larger ones subtract from the latter.

In addition to its role as a numeric symbol, DXLII or its lowercase variant may appear as an alphanumeric designation in various contexts. It can be used to label years, chapters, volumes, or product variants in systems that employ Roman numerals for organization or sequencing. Because DXLII is simply a numeral, its specific meaning depends on the source and context in which it appears.

DXLII does not denote a single, widely recognized entity on its own. When encountered in texts or catalogs, it typically functions as a numeric label or part of a longer designation, rather than as an independent name. The interpretation of DXLII thus requires contextual information such as the domain (historical dating, publishing, manufacturing, or software) and the accompanying nomenclature.
