0 a way of writing very large or very small numbers by putting one number before the decimal point, then multiplying by a power of 10, e.g. 3.6 x 10³ -- 科學計數法
Scientific notation was created to handle very small and very large numbers.
New topics sometimes include scientific notation, concepts with negative numbers, and more advanced geometry.
Exponentiation with base 10 is used in scientific notation to denote large or small numbers.
There is currently no satisfactory solution to this problem of notation without resorting to the use of scientific notation.
Scientific notation may be used as an alternative to the radix point.
However, megagram (and gigagram, teragram, etc.) are rarely used; tonnes (and kilotonnes, megatonnes, etc.) or scientific notation are used instead.
A number written in scientific notation has a significand (sometime called a mantissa) multiplied by a power of ten.
Decimal fractions can also be expressed using scientific notation with negative exponents, such as, which represents 0.0000006023.
