ISSUE: 4731
|
|
TITLE: Enhancement in precision of calculations with NUMERIC/DECIMAL
|
|
DESCRIPTION:
|
|
NOTES:
|
|
After fix CORE-5700 ("DECFLOAT underflow should yield zero instead of an error"), 02-feb-2018, expected result was
|
|
changed: all expressions with "almost zero" result should NOT raise any error.
