I have an ill conditioned 8th order polinomial, where ration
among the coefficients are giantic in some cases, therefore,
in order to be able to have correct results I need to
calculate the numbers until 50 or may be 60-70 digits, and
plot them. But when I use VPA it adjusts its digit as much
as you want but also it converts your variable to a sym
which is not able to plot (and which is my main aim). I
tried to convert it to double, so that it could plot, but
then it again reduced the digits of the number to defaults
format (if i use format long reduces to 15 and otherwise to
4). and this is not helping me. I need your help, is there
anything that you can suggest?

Best wishes,
Kamran
