Description:
When manipulation a JSON column containing zero fraction floats, the floats are casted to integers.

How to repeat:
SET @j = '[1.0]';
SELECT JSON_ARRAY_APPEND(@j, '$', 2.0);

Expected results:

[1.0, 2.0]

Actual results:

[1, 2.0]

Notice how 1.0 is changed to 1 while 2.0 preserve.

Thanks for the bug report, Martin. This looks like the same problem as bug#88230, which should be fixed in the upcoming version 8.0.4. Closing this bug as a duplicate.
