%description
Libaec provides lossless compression of signed or unsigned integers
(samples) of sizes 1 to 32 bits wide. 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.

%description -n libaec0
Libaec provides lossless compression of signed or unsigned integers
(samples) of sizes 1 to 32 bits wide. 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.
Libaec implements Golomb Rice coding as defined in the Space Data
System Standard documents 121.0-B-2 and 120.0-G-2.
