    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.

    I.e., if a number x is too large for a representation () the power tower can be made one higher, replacing x by log 10 x, or find x from the lower-tower representation of the log 10 of the whole number. If the power tower would contain one or more numbers different from 10, the two approaches would lead to different results, corresponding to ...

    In number theory, Skewes's number is the smallest natural number for which the prime-counting function exceeds the logarithmic integral function ⁡ (). It is named for the South African mathematician Stanley Skewes who first computed an upper bound on its value.

    In decimal notation the nth power of ten is written as '1' followed by n zeroes. It can also be written as 10 n or as 1En in E notation. See order of magnitude and orders of magnitude (numbers) for named powers of ten. There are two conventions for naming positive powers of ten, beginning with 10 9, called the long and short scales. Where a ...

    x 1 = x; x 2 = x 2 for i = k - 2 to 0 do if n i = 0 then x 2 = x 1 * x 2; x 1 = x 1 2 else x 1 = x 1 * x 2; x 2 = x 2 2 return x 1 The algorithm performs a fixed sequence of operations ( up to log n ): a multiplication and squaring takes place for each bit in the exponent, regardless of the bit's specific value.
