I wrote a lot of the plot code and I think it only works with floats.
I don't think we implemented anything at all to automatically deal
with high precision.
As a workaround, if you have a function f you want to plot to high
precision, maybe do this:
R = RealField(500)
def wrap(x):
# x is a floating point number
return f(R(x))
plot(wrap, ...)
---
Alternatively, compute in any way you want (to very high precision) a
list v of pairs (x,y), then do "line(v)" to get a plot of that.
