I have a TI89 from my college days, and I also bought a Casio fx115ES scientific calculator which is allowed to be used in the FE exam. I like both of them just fine.

Thanks. Can either of these handle exponents greater than 99? Mine returns errors for any exponent of x^100 or greater. Also, if there's a number with a bunch of zeros and then a couple digits, like 1.20000000000000000000006543, it will just display 1.2. Can these larger display calculators handle the extra zeros?
Thanks again. I'll also look at MathCAD.
