Likewise, GraphicsMagick includes work by Richard Nolde which knows how to handle 16 and 24 bit floats. He actually wrote a full conversion suite between 16, 24, 32, and 64-bit floats. I only incorporated the specific functions that GraphicsMagick needs. This code has been in GraphicsMagick since 2008. The code has been verified on a wide-variety of CPU types.
24 bit floats are also important because they are supported in the TIFF file format, are supported by Photoshop, and because some GPUs (e.g. from AMD) support 24 bit floats.
