Starting quite exactly five years ago, this thread in the old forum may refresh your memories in this regard. (08-05-2017 04:36 AM)Gerson W. Barbosa Wrote: In the olden days I had no 41, but I did have a 15C which had all the 12 conditional tests, Gamma, complex mode and a few other thing the 41 lacked :-) Hmmm... then I think of a complete set of flag tests as provided by the '41. ;-) Here the old tricks may help for the one or other elegant solution in a 15C program. On the 67/97 I love things like F2? F2? for a FC?C test, or three consecutive tests for more obscure applications. Or even four, like in the linked thread. I think I remember there also was an artice in an HP Journal issue... (08-05-2017 04:36 AM)Gerson W. Barbosa Wrote: This has replaced what I had in Free42 (per Natural Selection). Fine. Let me know if you find any cases where – at least for x>0,5 – the 12th digit is off by more than 1 unit. I hope you don't. ;-) With the applied correction term (line 128 ff.) the error for x>2 should be less than 1 unit in the 13th place. Dieter |
