Details

The rules for parsing numeric values have changed:

1. a value consisting of digits without decimal point and exponent will
   be parsed as INTEGER;
2. a value consisting of digits and a decimal point will be parsed as
   DECIMAL;
3. a value consisting of digits, containing an exponent and possibly
   containing a decimal point, will be parsed as DOUBLE.

To do

• change the description of feature E011-03 (https://www.tarantool.io/en/doc/latest/reference/reference_sql/sql-features/)
• change the description of DOUBLE literals, add a new paragraph for DECIMAL literals (https://www.tarantool.io/en/doc/latest/reference/reference_sql/sql_user_guide/)

This is good news. I think it only affects SQL, in two places.
https://www.tarantool.io/en/doc/latest/reference/reference_sql/sql-features/
change the description of feature E011-03, and
https://www.tarantool.io/en/doc/latest/reference/reference_sql/sql_user_guide/
change the description of DOUBLE literals, add a new paragraph for DECIMAL literals.
