Marti,
I guess, you mean, "... done in floating point" :-)
I realized that I have a problem with the integer computation, when I attempted to use cmsDoTransform() in the objective function, which I passed to an optimizer for numerical minimization. Since the output of the transform is not continuous, but a quantized staircase, and since the optimizer did compute numerical derivatives with small deltas, it always got stuck in a local minimum, often far away from the actual minimum which it should find.
