They are not the same: Newton vs. digit-by-digit

Code:

/* decNumberSquareRoot -- square root operator                        */

/* loop                                                               */
/*   p := min(2*p - 2, maxp)     % p = 4,6,10, . . . , maxp           */
/*   precision p                                                      */
/*   approx := .5 * (approx + f/approx)                               */
/*   exit when p = maxp                                               */
/* end loop                                                           */

Thomas,

Many thanks. This algorithm stuff gets huge quickly as size is at a premium on WP34S I'd suppose. I'm tempted to key-in the Egbert routines and check convergence times versus the Newton as indicated by you although I have a feeling I would be at a disadvantage using program lines versus pre-compiled c-code? Am I correct?
