The numbers and display are way too huge. I need to be able to make them smaller. I don't see any settings for this calculator. And it doesn't rotate for use in landscape mode either.

got a question: what does "several thousand digits long mean?" as big as I want, or am I limited to just a few thousand of them? I am asking because any calculation that takes over 24 hours gives me an "bad expression". I'll return soon. left 3 stars because of this error... maybe I am expecting too big of a number?!?

For a very specific use, but it works great and is very polished.
