A LastX should not be required as the stack is filled with x, i.e. both X, Y, Z and T contain the current x-value. This is true for the Solve and Integrate functions of the 34C, 15C, the WP34s and probably other HPs as well.

Not for the HP-42S; it doesn't put anything on the stack when it calls the function, but instead passes the parameters through named variables.

Speaking of the HP-42S, it gets 12 correct digits in 7'12" with ACC=0, evaluating the function 2047 times.
