+wide signed or unsigned integers (samples). The library achieves best results
+for low entropy data as often encountered in space imaging instrument data or
+numerical model output from weather or climate simulations. While floating
+point representations are not directly supported, they can also be efficiently
+coded by grouping exponents and mantissa.")
