[New-bugs-announce] [issue39335] round Decimal edge case

[Hrvoje Abraham]

New submission from Hrvoje Abraham <ahrvoje at gmail.com>:

>>> from decimal import Decimal
>>> round(Decimal('-123.499999999999999999999999999999999999999999'))
-124.0

I would expect -123.0, even considering Py2 rounding convention details (away from zero), Decimal rounding convention (default rounding=ROUND_HALF_EVEN), floating point specifics...

Works as expected in Py3. Both Py2 and Py3 use same default Decimal rounding=ROUND_HALF_EVEN.

Could be I'm missing some detail...
