  2. Exponentiation - Wikipedia

    en.wikipedia.org/wiki/Exponentiation

    This definition of exponentiation with negative exponents is the only one that allows extending the identity + = to negative exponents (consider the case =). The same definition applies to invertible elements in a multiplicative monoid , that is, an algebraic structure , with an associative multiplication and a multiplicative identity denoted 1 ...

    en.wikipedia.org/wiki/Scientific_notation

    The displays of pocket calculators of the 1970s did not display an explicit symbol between significand and exponent; instead, one or more digits were left blank (e.g. 6.022 23, as seen in the HP-25), or a pair of smaller and slightly raised digits were reserved for the exponent (e.g. 6.022 23, as seen in the Commodore PR100).

    en.wikipedia.org/wiki/Power_symbol

    In the anime Dimension W, Kyouma Mabuchi wears a Happi with the power symbol on his back. In the television series Sense8, the hacktivist character Nomi has a tattoo of the power symbol behind her ear. The symbol, rotated clockwise by 90 degrees so it looks like a capital G, becomes part of the logo for Channel 5's programme The Gadget Show.

  7. Signed number representations - Wikipedia

    en.wikipedia.org/wiki/Signed_number_representations

    Biased representations are now primarily used for the exponent of floating-point numbers. The IEEE 754 floating-point standard defines the exponent field of a single-precision (32-bit) number as an 8-bit excess-127 field. The double-precision (64-bit) exponent field is an 11-bit excess-1023 field; see exponent bias.

  9. Exponent (linguistics) - Wikipedia

    en.wikipedia.org/wiki/Exponent_(linguistics)

    An exponent is a phonological manifestation of a morphosyntactic property. In non-technical language, it is the expression of one or more grammatical properties by sound. There are several kinds of exponents: Identity; Affixation; Reduplication; Internal modification; Subtraction
