Consider this example from the article where it asks you to calculate the limit of ln(1+h)/h as h tends to zero. Set h to be 10^(-17). The Android calculator reliably succeeds and gives the same answer as Mathematica. The iOS calculator reliably fails; at least it knows its limits and refuses to give even an approximate answer.
