We have previously established that if we pick alow or ahigh, the error can’t exceed one tick of the numerator, which works out to ± 1/b. As a practical example, if we’re trying to approximate r = 2 using b = 5, the best inexact solutions are 9/5 = 1.8 on the low side and 11/5 = 2.2 on the high side; they both have an error of 1/b = 0.2.
