The question https://ask.sagemath.org/question/43517/conflicting-sage-vs-wolfram-evaluation-of-a-limit/
brought the following question to mind: can you specify the precision to which a function is evaluated when plotting it? The particular ask.sagemath.org question involves a function which has "inherent numerical instability", as kcrisman says in his answer. For example, evaluating V(20, 1).n() will result in "ValueError: power::eval(): division by zero", but V(20,1).n(300) gives an actual number. Is there a way to pass the numerical precision to the plot function? (I am not an expert in the plotting code in Sage, but when I look at the plot code, I see the function "generate_plot_points" which calls float(f(...)). That makes me think that the available precision is fixed. But maybe I'm wrong.) -- John -- You received this message because you are subscribed to the Google Groups "sage-support" group.
