I have been using calclulators for over 10 years and never had a need to calculate all those digits but I can see that if you are a bean counter working at a large bean processing facility that might be important. Perhaps a more important question for the typical user is which calculator is easiest to learn how to use? How would you rate those calculators then? For you that might not be important but for most calculator users it is or should be.

Practically nobody is interested in calculating 99999^999. As for the HP 50g, we want to highlight the fact that the exact mode calculations are bound only by memory. Read this discussion

http://groups.google...bb15b51d8fab5a3, after reading it do you still think that it is not important for a calculator to calculate big numbers? Even for a typical user?

Also, when it takes more than a few seconds to solve a problem using a calclulator, there are better alternatives to using a calculator and they, are spelled M-A-T-H-E-M-A-T-I-C-A or M-A-P-L-E.

MATHEMATICA or MAPLE? No thanks, I prefer XCAS, MAXIMA, AXIOM, SAGE... Free software is power!

Also, because having the ability to see the intersection of two or three surfaces is important when setting up a multivariable calculus problem, which calculator excels in that capability?

On this subject the ClassPad is the best
