The Oxford English Dictionary comments that googol and googolplex are "not in formal mathematical use". Usage of names of large numbers Some names of large numbers, such as million , billion , and trillion , have real referents in human experience, and are encountered in many contexts, particularly in finance and economics.
Two numbers are "within an order of magnitude" of each other if their ratio is between 1/10 and 10. In other words, the two numbers are within about a factor of 10 of each other. [1] For example, 1 and 1.02 are within an order of magnitude. So are 1 and 2, 1 and 9, or 1 and 0.2.
Visualization of 1 trillion (short scale) A Rubik's cube, which has about 43 trillion (long scale) possible positions. Trillion is a number with two distinct definitions: 1,000,000,000,000, i.e. one million million, or 10 12 (ten to the twelfth power), as defined on the short scale. This is now the meaning in both American and British English.
For example, a billion is represented as 13 characters (1,000,000,000) in decimal format, but is only 3 characters (10 9) when expressed in exponential format. A trillion is 17 characters in decimal, but only 4 (10 12) in exponential. Values that vary dramatically can be represented and compared graphically via logarithmic scale.
Widespread sounding of the word occurs through the name of the company Google, with the name "Google" being an accidental misspelling of "googol" by the company's founders, [9] which was picked to signify that the search engine was intended to provide large quantities of information. [10]
Other countries also use a word similar to trillion to mean 10 12, etc. Whilst a few of these countries like English use a word similar to billion to mean 10 9, most like Arabic have kept a traditionally long scale word similar to milliard for 10 9. Some examples of short scale use, and the words used for 10 9 and 10 12, are
In linguistics, ordinal numerals or ordinal number words are words representing position or rank in a sequential order; the order may be of size, importance, chronology, and so on (e.g., "third", "tertiary").
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.
