50 digits precision handheld calculator is it achievable or not?

[walter b]

Hmmh, "achievable" is a lot nowadays. Even such a calculator, I guess. The more interesting questions are: In which time? At what cost? Which leads to the question: Is there an economical basis for making such a device (based on parts and products available)? I know too little about HW to be able to tell you the answers to those questions.

How do you get to assume that? Source of information??
