22E4

22E4 is an alphanumeric designation used in several distinct domains. There is no single, universally recognized definition, and the meaning of 22E4 depends on context.

In mathematics and computing, 22E4 is commonly interpreted as a representative of scientific notation, meaning 22 × 10^4, i.e., 220,000. Some programming languages accept 22e4 as a numeric literal; in other contexts, it may be treated as a string or identifier.

In science and biology, 22E4 may appear as a locus label, sample identifier, or internal catalog code within a laboratory, but such usage is not standardized and is specific to an institution.

In transportation or consumer products, 22E4 can serve as a route designation, model number, part code, or version label, with meanings defined by the issuing organization.

Because the term spans multiple domains, readers should provide domain and context to determine the correct interpretation. If you have a particular 22E4 in mind, specify the field and source.
