HP 35s. FIX affects precision - Pablo P (Spain) - 10-22-2010 Hi all, by accident I have found that FIX mode affects the precision in some calculations. FIX mode is used to control the number of decimal digits used in the display of numbers. Only to display them. But consider the next:
Insert this function in the equation list:
Set FIX to 3 and integrate the function between -5 and 2.88 Set FIX to 5 and integrate the function between -5 and 2.88. You will get 0.99801133646
Similar results, but not identical.

Re: HP 35s. FIX affects precision - Bart (UK) - 10-22-2010 Hi Pablo, Re: HP 35s. FIX affects precision - Pablo P (Spain) - 10-22-2010 Thanks Bart, I missed this feature. The manual explains it perfectly.
Re: HP 35s. FIX affects precision - Dieter - 10-22-2010 No, this is not a bug but a (quite useful) feature of the HP35s an other calculators with the HP Integrate. It was already implemented in the good old 34C, the first model with this function. Re: HP 35s. FIX affects precision - Karl Schneider - 10-22-2010 Dieter -- Very good explanation. I'd add that FIX/SCI/ENG as integration-accuracy settings on the HP-35s, HP-33s, and HP-48/49/50 series don't have the same meaning as those on the HP-34C through the HP-32SII.
