Examples of numbers written in Scientific Notation.

Scientific notation is a mathematical expression used to represent a decimal number between 1 and 10 multiplied by ten, so you can write large numbers using less digits.

An example of scientific notation is when you write 4 x 10³ for 4,000.

## scientific notation

a mathematical expression used to represent any decimal number as a number between one and ten raised to a specific power of ten (Ex.: 4.1 × 10 for 4.1, 4.1 × 10 for 41, 4.1 × 10 for 410, 4.1 × 10 for 0.41, 4.1 × 10 for 0.041): often used for approximate computations with very large or small numbers

## scientific notation

noun

A method of writing or displaying numbers in terms of a decimal number between 1 and 10 multiplied by a power of 10. The scientific notation of 10,492, for example, is 1.0492 × 10

^{4}.## scientific-notation

Noun

(*uncountable*)

- (mathematics) a method of writing, or of displaying real numbers as a decimal number between 1 and 10 followed by an integer power of 10
- (mathematics) an alternative format of such a decimal number immediately followed by E and an integer
*The number 0.00236 is written in scientific notation as*2.36Ã—10^{âˆ’3}*or as*2.36E-3*.*

## scientific notation - Computer Definition

The display of numbers in floating point form. The number (mantissa) is always equal to or greater than one and less than 10, and the base is 10. For example, 2.345E6 is equivalent to 2,345,000. The number following E (exponent) represents the power to which the base should be raised (number of zeros following the decimal point).
