For the record: a standard Romberg implementation like the one in the WP34s requires merely 61 function calls for the x² integral or 511 calls for 1/x to return results with full 16-digit accuracy. You really should switch to a better method. And virtually anything is better than rectangular or trapezoid. Dieter |
