Comment #3 on issue 1894 by mattpap: Xor(x, 1/y) doesn't work
http://code.google.com/p/sympy/issues/detail?id=1894
how do you compute 1/True and 1/False?
In [1]: 1/True
Out[1]: 1.0
In [2]: 1/False
ZeroDivisionError: float division
I just expect this two inputs should give the same result:
In [7]: 1/y & ~x
TypeError: unsupported operand type(s) for &: 'Pow' and 'Not'
In [8]: And(1/y, ~x)
Out[8]:
1
¬ x ∧ ─
y
(an expression or raise an exception). I don't mind Xor(x, 1/y) raising an
exception.
