It's an intermediate format for film and digital effects work in
linear RGB, linear YCbCr, or linear gray (with additional channels

With integer channels you might have a chance, but you can't convert
from floating-point to 16 bpc integer without clamping the input
somewhere, and the standard doesn't specify any reference points.
