-------------------------------------
Summary: ReadOnlyMemChunk round float\double data incorrectly
Key: IOTDB-443
URL: https://issues.apache.org/jira/browse/IOTDB-443
Project: Apache IoTDB
Issue Type: Bug
Components: Core/Engine
Affects Versions: 0.9.1
Reporter: Xiangdong Huang
In our design, only RLE and TS_2DIFF need float_precision to round the value.
However, when we read data from memory, all float\double data will be rounded,
even if it uses Gorilla encoding.
e.g., suppose root.sg1.d1.s1 is double datatype and Gorilla encoding. The
float_precision=1.
If we insert a value (t,s1) = 1, 1.123, and select the data, we will get 1.1.
However, if we run `flush` after insert the data, and then select the data, we
will get 1.123.
How to fix: we need to modify the init() method in ReadOnlyMemChunk to check
the encoding method first.
