Something that seems a little counter-intuitive to me (having now worked with the assumptions a bit) is the decision to let 2, I and 2 + I all be considered complex (with the former two being real and imaginary, also, respectively). It seems like it would be more useful to consider them be onlny real, imaginary and complex, resepectively.
Is there a reason for doing so? The way it is right now, the only way to say that something has a non-zero real and imaginary part is to write it as a + I*b, e.g. ask(Q.real(I**(a + I*b)), Q.real(a) & Q.real(b)) instead of ask(Q.real(I**c), Q.complex(c)). -- You received this message because you are subscribed to the Google Groups "sympy" group.
