Generally, the order of magnitude of a number is the smallest power of 10 used to represent that number.[2] To work out the order of magnitude of a number N, the number is first expressed in the following form:
N = a × 10^b
where 1/sqrt(10) ≤ a < sqrt(10) . Then, b represents the order of magnitude of the number.
