7e

7E is an alphanumeric designation that can refer to several unrelated concepts depending on context. It does not have a single universally recognized meaning beyond its use as a label in various systems.

In computing and data formats, 0x7E (hex) corresponds to the ASCII tilde character "~", a common symbol in programming and text processing. The form 7E can also appear in scientific notation to represent 7 times 10 to the power of an exponent, as in 7e3 equals 7000.

In aerospace, Boeing used the internal designation 7E7 for the development program of the aircraft that would become the 787 Dreamliner; documentation and media from the program sometimes refer to it as 7E7. The 7E7 name is historical and not used for the production model.

Outside of specific technologies, 7E appears in product codes and model numbers across industries, serving as a short label in parts, editions, or regional identifiers. Because it is a generic alphanumeric sequence, its precise meaning is determined by the particular domain or document in which it appears.
