A range of a real number x is an interval [a, b] of a given length that contains x.

The length of this interval is called the amplitude or order of magnitude of this range.


The interval [3.14; 3.15] is a range, to the nearest hundredth, of the real number π and the amplitude of this interval is 0.01.
