Originally NoteCalc used a library for handling arbitrarily large numbers. Unfortunately, some operations were so slow that as a quick fix, I replaced the library with a lighter one without dynamic allocations (which is 96 bit integer with 28scale).

This serves well the primary goal of NoteCalc so I did not spend more time on it yet, but I am on the same page as you, and if NoteCalc will be feature-complete, I will give an other shot to arbitrarily large calculations/precision.
