Hi, Here is a branch that fixes a number of issues with Relational and Interval:
* Relationals of numbers now evaluate immediately to a bool (Eq(0,0) -> True) * Intervals and other Sets will not raise a TypeError if Set.contains returns a non bool. This is to prevent Set.__contains__ (which casts the result of Set.contains to a bool) from returning meaningless results like x in Interval(0,1) == True. http://github.com/ellisonbg/sympy/tree/bg-relational All tests pass and I have added new tests to check the fixes. Thanks everyone for you help in ironing out these issues. Cheers, Brian -- You received this message because you are subscribed to the Google Groups "sympy-patches" group.
