Comment #2 on issue 1868 by mattpap: solve(floating point, x) stopped
working
http://code.google.com/p/sympy/issues/detail?id=1868
This is fixed in polys8 branch. Note that it's better to use nroots()
function to get
numerical approximations of roots of the input polynomial (nroots()
utilizes mpmath's
root finding algorithm), e.g.:
In [1]: EQN1 = -12.0* 12.0*(2*sqrt(3.0) + 9.0) + (78.0 + 24.0*sqrt(3.0)
)*x**2 -
3.0*sqrt(2.0) * x**3 - x**4
In [2]: EQN1
Out[2]:
2 3 4
-1794.83063257984 + 119.569219381653⋅x - 4.24264068711929⋅x - x
In [3]: nroots(EQN1)
Out[3]: [-12.7530479110482, -3.85012393732929, 4.89897948556636,
7.46155167569183]
