Does the new 33S have the same accuracy as the 30S? Message #1 Posted by Roy on 27 Mar 2004, 4:21 p.m. The HP30S does calculations to 24 places...does the new 33S also do that? An easy way to tell is to calculate 3^201..then subtract from that 7.968419666 E 95 and if the result strats with 276 then it has the extra accuracy. thanks.

Re: Does the new 33S have the same accuracy as the 30S? Message #2 Posted by Wlodek Mier-Jedrzejowicz on 27 Mar 2004, 8:49 p.m., in response to message #1 by Roy The HP33S is mostly an emulator of the HP32SII, and like the HP32SII it works to 12 digit precision, with exponents between -499 and +499. Internally it copies the HP32SII too, with 15 digit precision and 5 digit exponents. So the result of the calculation is 260, not 276. The HP30S has wonderful precision if that's all you need :-) Wlodek

[33S is an emulation??] Message #3 Posted by Bill Wiese on 28 Mar 2004, 8:14 p.m., in response to message #2 by Wlodek Mier-Jedrzejowicz Hi folks.. So do we really know that the 33S is an emulation of the 32S CPU? That is, there's a little byte-code interpreter running on its 6502, fetching Saturn code, and appropriately patched for new I/O architecture?? Thanks, Bill Wiese San Jose CA

[33S is an emulation??] Message #4 Posted by Arnaud Amiel on 29 Mar 2004, 5:16 a.m., in response to message #3 by Bill Wiese The fact that the 33s does not give exactly the same results as the 32sII would make me believe that it is not a CPU emulation as in the 49g+ which gives the same results as the 49G.
