I think the problem with the "99+" answers comes from the expression e^(1/x)^3. As written it's ambiguous, giving different answers depending on whether the powers are evaluated left-to-right (\({\rm e}^{3/x}\)) or right-to-left (\({\rm e}^{1/x^3}\)). The WP34S gives the correct answer when provided with the correct input, and I expect the TI machines will too.
