ISSUE:       6578
TITLE:       SubType information is lost when calculating arithmetic expressions
DESCRIPTION:
JIRA:        CORE-6337
FBTEST:      bugs.core_6337
NOTES:
    [25.06.2020]
        4.0.0.2076: changed types in SQLDA from numeric to int128 // after discuss with Alex about CORE-6342.
    [13.12.2023] pzotov
        Added 'SQLSTATE' in substitutions: runtime error must not be filtered out by '?!(...)' pattern
        ("negative lookahead assertion", see https://docs.python.org/3/library/re.html#regular-expression-syntax).
        Added 'combine_output = True' in order to see SQLSTATE if any error occurs.
