Yes, and that's perfectly OK according to what I gathered Home and CAS view is intended for, i.e Home for approximate calculations on "real" numbers, and CAS for "exact" analysis.

(I use RPN in Home view, but it doesn't affect the integer precision.)

But calculations on large precision integers aren't the kinds of mathematics CAS is suitable for, either. I'd use CAS for algebra or calculus.

Maybe this is just one of the things done more easily on the hp50g, then? If I just had the speed of the Prime on it! ;-)
