In Mul class I see this piece of code: def _eval_is_real(self): real = True zero = one_neither = False
for t in self.args: if not t.is_complex: return t.is_complex Don't understand last two lines. How is it possible that if t is not complex, then return that all Mul is not real? -- You received this message because you are subscribed to the Google Groups "sympy" group.
