DeskCalc could be made to use some arbitrary accuracy independent of
the window size, in fact, that is how it worked before I began (32
digits). But then the result may or may not fit in the text view which
is ugly, the cursor gets put at the rightmost end of the result
(correctly) but that is ugly because you can't see the beginning of
the result without resizing or scrolling. Scrolling is of course an
option but doesn't really solve the underlying problem.
I could see imposing a maximum precision (lets say 32 digits) and not
calculating beyond that no matter what your window size is but I don't
see a reason why I should. Most users won't notice or care, for the
few who want more accuracy they'll be able to get it. Either way the
result will fit in the text view and look nice.
