  2. Order of magnitude - Wikipedia

    en.wikipedia.org/wiki/Order_of_magnitude

    The different decimal numeral systems of the world use a larger base to better envision the size of the number, and have created names for the powers of this larger base. The table shows what number the order of magnitude aim at for base 10 and for base 1 000 000 .

    1/52! chance of a specific shuffle Mathematics: The chances of shuffling a standard 52-card deck in any specific order is around 1.24 × 10 −68 (or exactly 1 ⁄ 52!) [4] Computing: The number 1.4 × 10 −45 is approximately equal to the smallest positive non-zero value that can be represented by a single-precision IEEE floating-point value.

  6. Power of 10 - Wikipedia

    en.wikipedia.org/wiki/Power_of_10

    Where a power of ten has different names in the two conventions, the long scale name is shown in parentheses. The positive 10 power related to a short scale name can be determined based on its Latin name-prefix using the following formula: 10 [(prefix-number + 1) × 3] Examples: billion = 10 [(2 + 1) × 3] = 10 9; octillion = 10 [(8 + 1) × 3 ...

    The financial and general news media mostly use m or M, b or B, and t or T as abbreviations for million, billion (10 9) and trillion (10 12), respectively, for large quantities, typically currency [28] and population. [29] The medical and automotive fields in the United States use the abbreviations cc or ccm for cubic centimetres.
