Convert numbers to scientific notation and significant figures
Scientific notation is a way of expressing numbers in the form a × 10n, where 1 ≤ a < 10 and n is an integer. This notation is useful for representing very large or very small numbers. For example, the number 456,000 can be written as 4.56 × 105 in scientific notation. (Wikipedia)
Significant figures are a way of representing the precision of a number. The number of significant figures in a number is the number of digits that are known to be reliable. For example, the number 456 has 3 significant figures, while the number 456.0 has 4 significant figures. (Wikipedia)
