> file an image which is in a float** ?

See http://magick.imagemagick.org/script/formats.php for the TIFF and raw
formats such as RGB.  You will need a recent version of ImageMagick to
properly recognize the –depth 32 –define quantum:format floating-point
options.

You can use the new stream program to output floats.  ImageMagick
6.2.8-1 is required.
