Data compression library based on Jointed Hierarchical Precision
Compression Number - Data Format
JHPCN-DF is a novel lossy compression algorithm taylored for floating
point dataset. The algorithm enhances the effect of employing standard
compression algorithms like deflate because this approach makes
the occurence rate of the same byte pattern in data stream higher owing
to truncating some lower bits of significand.
