  3. Scientific notation - Wikipedia

    en.wikipedia.org/wiki/Scientific_notation

    While base ten is normally used for scientific notation, powers of other bases can be used too, [25] base 2 being the next most commonly used one. For example, in base-2 scientific notation, the number 1001 b in binary (=9 d) is written as 1.001 b × 2 d 11 b or 1.001 b × 10 b 11 b using binary numbers (or shorter 1.001 × 10 11 if binary ...

  5. Engineering notation - Wikipedia

    en.wikipedia.org/wiki/Engineering_notation

    Engineering notation or engineering form (also technical notation) is a version of scientific notation in which the exponent of ten is always selected to be divisible by three to match the common metric prefixes, i.e. scientific notation that aligns with powers of a thousand, for example, 531×10 3 instead of 5.31×10 5 (but on calculator displays written without the ×10 to save space).

    en.wikipedia.org/wiki/Greek_letters_used_in...

    Greek letters are used in mathematics, science, engineering, and other areas where mathematical notation is used as symbols for constants, special functions, and also conventionally for variables representing certain quantities. In these contexts, the capital letters and the small letters represent distinct and unrelated entities.

  7. Normalized number - Wikipedia

    en.wikipedia.org/wiki/Normalized_number

    In applied mathematics, a number is normalized when it is written in scientific notation with one non-zero decimal digit before the decimal point. [1] Thus, a real number, when written out in normalized scientific notation, is as follows:
