ISSUE: 5963
|
|
TITLE: Conversion from zero numeric literals to DECFLOAT results in incorrect value
|
|
DESCRIPTION:
|
|
Confirmed wrong output from table with decfloat16 field (in WI-T4.0.0.1047, date of build: 03-JUL-2018).
|
|
Confirmed overflow of decfloat34 when inserting values with exponent more than 385, i.e. >= 1e+385 or <= -1e385 (in WI-T4.0.0.1535, date of build: 24-JUN-2019)).
|
|
Checked on 4.0.0.1556: OK, 1.710s.
