Im() of negative non-complex numbers is pi (PR#8272)

Sorry, I meant to write 2.1.1 instead of 2.2.1 below.

Hi,

I think the following indicates a bug in Im().

Im(-1)
[1] 3.141592653589793115998
pi
[1] 3.141592653589793115998
Im(0i-1)
[1] 0
Im(-0.9876)
[1] 3.141592653589793115998
Im(-987654321)
[1] 3.141592653589793115998
Im(1)
[1] 0
is.complex(-1)
[1] FALSE

This is R 2.2.0; Im(-1) == 0 with R 2.2.1.

Thanks,

Dan
