Calculating Lower and Upper Bounds of 100 to 2 Significant Figures
Since anything between 100 and 105 rounded to 2 significant figures would be 100, logically the upper bound is 105. On the other hand, the lower bound cannot correspondingly be 95 because 95 to 2 significant figures is 95! Therefore, should it be that in this case: $99.5 \le x \lt 105$? If so, that rather lacks the symmetry I had expected.
