Re: Some 49G+ Limitations Message #9 Posted by Ralph on 10 Feb 2005, 2:33 p.m., in response to message #8 by John Smitherman
After reading all these discursions about how calculators handle 'extremes' these are the results for the following functions on a HP65, HP41CX and HP48G:
a)1000!
HP65(9.999999999E99) wich is interpreted as an overflow
HP41CX(OUT OF RANGE)
HP48G the same as stated for the HP49G+
b)1.5!
HP65 -display blinks
HP41CX (DATA ERROR)
HP48G the same as stated for the HP49G+
c)asin(acos(atan(tan(cos(sin(7))))))
HP65(7.003719916) worse than HP49G+, HP48G and HP41CX
HP41CX(6.999519575) worse than HP49G+, HP48G
HP48G the same as stated for the HP49G+
Certainly the results improve with the newer models, but a strange thing for case c), HP41CX gives a result that aproaches from under the correct value, instead of all others.
