floor() isn't particularly well-defined in CC. I guess we could just
round each .real and .imag component down to the next lowest integer
and define Z1 % Z2 to be the remainder from that. The operations don't
really make sense for most elements in CC, but it "smoothly"
extrapolates from the RR results.
