#                   NOTE. Results for FB 4.0 become differ from old one. Discussed with Alex, 30.10.2019.
#                   Precise value of 70000 / 1.95583 is: 35790.431683735296 (checked on https://www.wolframalpha.com )
#                   Section 'expected-stdout' was adjusted to be match for results that are issued in recent FB.
#                   Discuss with Alex see in e-mail, letters 30.10.2019.
#                   Checked on:

#                   changed subtype from 0 to 1 for cast (-70000 as numeric (18,5)) / cast (1.95583 as numeric (18,5))
#                   (after discuss with dimitr, letter 21.06.2020 08:43).
#
#                   25.06.2020, 4.0.0.2076: changed types in SQLDA from numeric to int128 // after discuss with Alex about CORE-6342.
