WI-T3.0.0.31844
C:\MIX\firebird\QA\fbt-repo\tmp>isql -q
SQL> set sql dialect 1;
SQL> create database 'c:\temp\c1712dia1_emb.fdb';
SQL> select cast(1e19 as varchar(30)) from rdb$database;
CAST
==============================
1.000000000000000e+19
SQL> exit;
C:\MIX\firebird\QA\fbt-repo\tmp>isql -q
SQL> set sql dialect 1;
SQL> create database 'localhost/3333:c:\temp\c1712dia1_tcp.fdb';
SQL> select cast(1e19 as varchar(30)) from rdb$database;
CAST
==============================
1.000000000000000e+019
Note that when TCP is used than exponent is '+019' -- with leading '0' left
side from '19'.
The same will be if we use existent database instead of creating it.
