Independent of whatever the spec claims or not, it is a fact that this calculator has bugs in its basic floating point operations. Caveat emptor if you want to use this calculator for any important computations.

Certainly "Caveat calculator" when the calculator (in Latin he was a person, female calculatrix) uses an electrical friend to calculate.

The Canon machine is still better than using extended reals in the HP 48G - I've tested this. As for comparisons of most calculation results on the current offerings I'd like to know more.
