This is an open discussion. Software requirement and hardware that would be the size of a mobile phone. My interest is pure entertainment. This was sparked by my new found interest in homebrew calculators and the complexity of the technology.

I think that the hp42s has 25 digits internal precision. Please correct me if I am wrong and the hp 50g is 15 digits.

I don't see why a calculator could not handle 50 digit precision.
