Comment (by Balling):

 I mean the patch does make sense: the floating point doesn't have a color
 range, because color range is also called quantization range, and
 quantization is the process of transforming float to integer. Float thus
 has not range.

 But then again as I understand our float to integer and vice versa is not
 perfect.
