RE: Just received a HP35s

I prefer its 2-line display to the single line of my 15CLE, and it's less cumbersome for run of the mill calculations than my 50g. That's exactly my impression as well.

With everyday use, a battery set lasts for more than a year. I think that's far from "heavy consumption".

As an engineer working on practical projects, I rarely need more than about three siginificant figures in the mantissa, but an error by a factor of 10 could be serious. I think we should not blame the 35s here. In any case it displays an "E" at the right display border, so you know there is an exponent – yes, it's out of the display, and I also do not like the switch to SCI display for any value below 1 (that's why I use the WP34s in ALL 3 mode). But with the limited number of display digits there is no other choice except reducing the mantissa digits. Remember, the mode is called ALL, not MOST or SOME. ;-) (02-06-2015 10:31 AM)Derek W Wrote: As an engineer working on practical projects, I rarely need more than about three siginificant figures in the mantissa, but an error by a factor of 10 could be serious. Then simply set the 35s to SCI 3 or ENG 3, or use its default setting FIX 4. That's what worked for generations of 67/97/41C/15C users – they simply had no ALL mode.

It's a pity that the (real) bugs were not detected during tests before production started. I wonder what kind of tests HP did (or usually does) before a calculator is ready to be marketed. Maybe someone with insight may comment on this. Dieter |
