Issue 1150: Basic.is_fraction docstring missing
http://code.google.com/p/sympy/issues/detail?id=1150
New issue report by goriccardo:
In [1]: x.is_fraction()
Out[1]: True
In [2]: (x+1).is_fraction()
Out[2]: True
In [3]: (x+y).is_fraction(x)
Out[3]: True
In [4]: (sin(y)/x).is_fraction()
Out[4]: False
In [5]: (sin(y)/x).is_fraction(x)
Out[5]: True
I think it's not so clear when it should return False.
A docstring could be useful
