Scientific notation

Scientific notation is a common number notation used to express large and small numbers in the form \(x \times 10^y\), where \(1 \leq |x| < 10\) and \(y \in \mathbb Z\). Mathworld by Wolfram.

== Examples ==
* \(1\times10^2\) = 100
* \(1.234\times10^3\) = 1,234
* \(9.5\times10^4\) = 95,000
* \(86.4\times10^7\) = 86,400,000
* \(1\times10^{10}\) = 10,000,000,000
* \(1\times10^{27}\) = octillion
* \(1\times10^{100}\) = googol
* \(1\times10^{303}\) = centillion
* \(1\times10^{1,000,000}\) = milliplexion
==Growth rate==
Scientific notation can express numbers that can be produced with the \(f_2 (n)\) function of the fast-growing hierarchy.
==Values in other notations==
values for \(a\times(10^{b})\)
Notation 	Equal value
Arrow notation	\(a\times 10\uparrow b\)
BEAF 	\(a\times\{10,b\}\)
