unsure as to why you would be getting banding rendering out ar 32bit.

Are you sure you have your framebuffer set at RGBA 32bit Float?

Are you using a exposure lens shader at all? If so try removing it.

Turn on Jitter in the render settings. This option is normally used to minimise banding in 8bit images but might also help in your image.
