I thought plotting are just some arithmetical operations for around
hundret points, why can it slow down so much by using RR or QQ?
Or do the functions to be plotted consume the most of the time if they
are not computed with floats?

As I now see, the problem might not have directly to do with
truncation to floats, I provide the following simple example:

parametric_plot((lambda x: log(x),lambda x: log(x)**2),(2**(-50),0.5))

this has an ugly break a bit below x=-10.
