Comment #2 on issue 2964 by [email protected]: S.One.is_prime gives True http://code.google.com/p/sympy/issues/detail?id=2964
S.One should certainly not be prime. But this is an assumptions system issue. The is_prime function computes the primality of its argument:
[(i, isprime(i)) for i in range(5)]
[(0, False), (1, False), (2, True), (3, True), (4, False)] -- You received this message because you are subscribed to the Google Groups "sympy-issues" group.
