1. this pr is used to optimize the export precision of floating point
numbers.
2. before the change, it will return the result that lost of precision when
we import floating point numbers and use array function to query.
MySQL> select a8[1], a9[1] from array_test_table where k1 = 1;
+----------------------------+----------------------------+
| %element_extract%(`a8`, 1) | %element_extract%(`a9`, 1) |
+----------------------------+----------------------------+
| 0.000247 | 0.014173 |
+----------------------------+----------------------------+
3. after the change, it could return the precise result when we import
floating point numbers and use array function to query.
