+
+    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.
