23e

23e is a short alphanumeric string that, on its own, has no single definition. In practice, it serves as a label or identifier across diverse domains, including manufacturing, transportation, data labeling, and fictional works. Because the same string can be generated by different conventions, its meaning is determined by context.

In cataloging and product labeling, 23e may denote a particular model, variant, or lot within a series. It is common for manufacturers to use sequences of digits with optional letters to distinguish versions, configurations, or revisions.

In transportation planning, alphanumeric codes such as 23e can designate routes, services, or stops. The exact meaning depends on the city or agency that assigns the code.

In computing and data science, the letter e is used to indicate exponent in scientific notation, as in 2.3e2 meaning 2.3 × 10^2. However, 23e by itself is not a valid standalone numeric literal; it would normally appear as part of a larger token such as 2.3e1 or 23e-4. In datasets or filenames, 23e could be part of an identifier or an obfuscated string rather than having intrinsic meaning.

In biology or genetics, alphanumeric strings are common in sequence tags or accession numbers, but 23e would typically be an arbitrary label rather than a standardized symbol.

Because 23e lacks an isolated, universal meaning, clarification of the intended domain is helpful to determine its precise interpretation.
