Very cool. I think we should mention thi example in the docs as well?

Well, Numpy's poly1d will work fine wit

Hello,
I've been working with numpy's poly1d class recently, and it would be
very useful to me if the class worked with fractions instead of
floats (since I'm encountering quantities that often mostly cancel out,
which lead to instabilities in my algorithms; hence it would be
useful to use fractio
