New issue 1603 by smichr: mpmath doesn't directly accept sympy numbers
http://code.google.com/p/sympy/issues/detail?id=1603
I wonder if mpmath should more easily accept sympy numbers. I don't use it
that often so I'm unsure of the current philosophy:
>>> mpmath.polyroots((1,2))
[mpf('-2.0')]
>>> mpmath.polyroots((S(1),S(2)))
Traceback (most recent call last):
File "<interactive input>", line 1, in <module>
File "C:\Documents and Settings\chris\sympy\sympy\mpmath\calculus.py",
line 1519, in polyroots
lead = mpmathify(coeffs[0])
File "C:\Documents and Settings\chris\sympy\sympy\mpmath\mptypes.py",
line 363, in convert
raise TypeError("cannot create mpf from " + repr(x))
TypeError: cannot create mpf from 1
