Let's not forget that the Romberg method is based on the Trapezoidal rule. It just does a clever extrapolation based on a quite good error estimate. ;) FWIW, I think something like the Trapezoidal method or even the much better Simpson rule really should not get implemented in a current calculator. That's like calculating trig and log functions with just five significant digits. My first calculator back in 1977 did so, but some things have changed since then. ;) Dieter
