Comment #3 on issue 2684 by ronan.l...@gmail.com: Deepcopy does not work on evaluate False http://code.google.com/p/sympy/issues/detail?id=2684 Actually, __reduce__ and __reduce_ex__ bypass the standard pickling and copy protocols, so it would be nicer to avoid using them. However,

Hi, I was browsing the code in residue_ntherory.py and found that in SymPy, legendre_symbol can have only two values { -1, 1 } out of the possible set { -1, 0, 1} [0]. I made the necessary change ( changed 'if' condition) and added a test for the same [1] but haven't made a pull request yet.

instead of `a%p` write `a % p`. Also, since this will have to be computed again later you might as well do both at the same time: a, r = divmod(a, p) if not r: return 0 if is_quad_residue(a, p): return 1 else: return -1 -- You received this message because you are subscribed to the
