Comment #3 on issue 2116 by nicolas.pourcelot: -LambertW(-1) is not real http://code.google.com/p/sympy/issues/detail?id=2116
In isympy, using "$ env SYMPY_USE_CACHE=no bin/isympy": In [1]: LambertW(-1).is_real In [2]: (-LambertW(-1)).is_real Out[2]: True In [3]: LambertW(-1).is_real So, LambertW(-1).is_real always returns None now. But there is still an issue with (-LambertW(-1)).is_real. -- You received this message because you are subscribed to the Google Groups "sympy-issues" group.
