As a result, the order in which things are declared in a program can have possibly surprising effects on things like declaration emit.
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.
