  2. Positional notation - Wikipedia

    en.wikipedia.org/wiki/Positional_notation

    Digits to the right of it are multiplied by 10 raised to a negative power or exponent. The first position to the right of the separator indicates 10 −1 (0.1), the second position 10 −2 (0.01), and so on for each successive position. As an example, the number 2674 in a base-10 numeral system is: (2 × 10 3) + (6 × 10 2) + (7 × 10 1) + (4 ...

  3. Work (physics) - Wikipedia

    en.wikipedia.org/wiki/Work_(physics)

    If an object with weight mg is displaced upwards or downwards a vertical distance y 2 − y 1, the work W done on the object is: = = = where F g is weight (pounds in imperial units, and newtons in SI units), and Δy is the change in height y. Notice that the work done by gravity depends only on the vertical movement of the object.

  5. Notation system - Wikipedia

    en.wikipedia.org/wiki/Notation_system

    Positional notation also known as place-value notation, in which each position is related to the next by a multiplier which is called the base of that numeral system Binary notation, a positional notation in base two; Octal notation, a positional notation in base eight, used in some computers; Decimal notation, a positional notation in base ten

  6. Negative base - Wikipedia

    en.wikipedia.org/wiki/Negative_base

    A negative base (or negative radix) may be used to construct a non-standard positional numeral system.Like other place-value systems, each position holds multiples of the appropriate power of the system's base; but that base is negative—that is to say, the base b is equal to −r for some natural number r (r ≥ 2).

  7. Unary numeral system - Wikipedia

    en.wikipedia.org/wiki/Unary_numeral_system

    The unary numeral system is the simplest numeral system to represent natural numbers: [1] to represent a number N, a symbol representing 1 is repeated N times. [2]In the unary system, the number 0 (zero) is represented by the empty string, that is, the absence of a symbol.

  9. Bit numbering - Wikipedia

    en.wikipedia.org/wiki/Bit_numbering

    Bit indexing correlates to the positional notation of the value in base 2. For this reason, bit index is not affected by how the value is stored on the device, such as the value's byte order . Rather, it is a property of the numeric value in binary itself.
