+        HdrHistogram supports the recording and analyzing sampled data value
+        counts across a configurable integer value range with configurable value
+        precision within the range. Value precision is expressed as the number of
+        significant digits in the value recording, and provides control over value
+        quantization behavior across the value range and the subsequent value
+        resolution at any given level.
