- 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.
- (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 2.36×10−3 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).
