    This may sound odd when compared with casing of Latin (and some other)
    letters, but it can be argued that casing can make a semantic distinction
    for letters (e.g., separating a generic noun from a proper noun), whereas
    for digits, casing is stylistic and does not affect meaning.

    Moreover, casing of digits is usually the same across a piece of text, i.e.
    you use either lowercase digits or uppercase digits throughout the text.
    This supports the idea that it’s stylistic variation, comparable to the
    choice of a font (and quite often made through the choice of a font).
