  • $\begingroup$ I just now realized this is basically the same as Daniel suggests in the answer @xzczd linked to... $\endgroup$ Commented Nov 8, 2012 at 8:03
  • $\begingroup$ @sebhofer... that's pretty cool. I'm trying to read Daniel's answer but since it has details of the other question, it is not immediately clear to me why Rationalize reduces any numerical instability or other issues. If you can expand a bit on why Rationalize works then that would be awesome Thanks $\endgroup$ Commented Nov 8, 2012 at 8:33

  • $\begingroup$ @b.gatessucks whoa.. I got {-3.67838*10^-9, 208.209} when I tried {f1, f2} /. fr. Whats going on? $\endgroup$ Commented Nov 8, 2012 at 8:56

    $\begingroup$ 囧…after changing the Rationalize[…, 0] in sebhofer's code into SetPrecison[…, Infinity], I get the correct result as @b.gatessucks … I don't know the exact reason though… $\endgroup$ Commented Nov 8, 2012 at 13:23
