Hello,

I think I tried to post this about an hour ago, but the discussion
didn't show up. So I'm doing it again, sorry in case it is repeated.

I am working in sage 3.4.1

I am trying to define a function to get the LaTeX string of a graph,
so I am trying to convert a number to string.

I have x=6.1230317691118863e-17, which I got from

sage: x=graphs.PetersenGraph().get_pos()[0][0]

I would like a two decimal approximation of x, that is 0.00.

I have tried

sage: numerical_approx(x,digits=2)
6.1e-17
sage: n(x,digits=2)
6.1e-17

Is there a way to get 0.00 as output?

Thanks in advance for your attention and help.

Greetings,
Fidel
