50 digits precision handheld calculator is it achievable or not?

[Gjermund Skailand]

Hi
I wrote the longfloat Library years ago.
I have a (alpha) version in hpgcc3 R002 based on the decnumber library.
This has complex math of standard functions including (inverse) trigometric and hyperbolic functions.
It is *much* faster, but require that you install an upgraded rom in order to run hpgcc3. There is no support for intervall arithmetic. There is no support for automatic function evaluation.
There are issues with rounding of results which I didn't manage to solve. Thus to make a finished product it requires help from one who is proficient in hpgcc3 and decnumber... and there are not many such people around.

Best regards
