Conversion from numeric literals to DECFLOAT adds precision that is not
originally present
------------------------------------------------------------------------------------------
Key: CORE-5697
URL: http://tracker.firebirdsql.org/browse/CORE-5697
Project: Firebird Core
Issue Type: Bug
Environment: Firebird-4.0.0.840-0_x64 (on Windows 10 x64)
Reporter: Mark Rotteveel
When inserting into a table with a DECFLOAT(16) column,
Using
insert into decfloat16 (column1) values (1E300);
insert into decfloat16 (column1) values ('1E300');
and then select cast(column1 as varchar(30)) from decfloat16 will result in:
1.000000000000000E+300
1E+300
In other words, the conversion from literal adds 15 digits of precision that
weren't actually present in the literal.
