ISSUE:       5992
TITLE:       Unclear error message when inserting value exceeding max of dec_fixed decimal
DESCRIPTION:
  FB40SS, build 4.0.0.1008: OK, 1.641s.
  Previously used:
      create table extdecimal( dec34_34 decimal(34, 34) );
      insert into extdecimal values(1);
  -- and this raised following exception:
      SQLCODE: -901
      Decimal float invalid operation.  An indeterminant error occurred during an operation.
      numeric value is out of range
  ==================================
  Since 30.10.2019 DDL was changed:
    create table test(n numeric(38,38) );
    insert into test values( 1.70141183460469231731687303715884105727 ); -- must PASS
    insert into test values( 1.70141183460469231731687303715884105727001 ); -- must FAIL.
  Explanation:
    1.70141183460469231731687303715884105727 represents
    2^127-1 // 170141183460469231731687303715884105728-1

  Checked on:  4.0.0.1635
NOTES:
[25.06.2020]
  4.0.0.2076: changed types in SQLDA from numeric to int128 // after discuss with Alex about CORE-6342.
JIRA:        CORE-5726
