# scientific notation

Standard scientific notation represents a number as a factor multiplied by a power
of 10; 3,560,000 is expressed as 3.56 × 10^{6}. This is useful for very large and very small numbers, especially in non-SI units.
You can also use certain standard prefixes, many of which are listed here with their
abbreviations.
