Subject: [PATCH]  Fix interpret decimal.Decimal object as an integer

Ref: https://docs.python.org/3.8/whatsnew/3.8.html

Many builtin and extension functions that take integer arguments will
now emit a deprecation warning for Decimals, Fractions and any other
objects that can be converted to integers only with a loss (e.g. that
have the `__int__()` method but do not have the `__index__()` method).
In future version they will be errors. (Contributed by Serhiy
Storchaka in bpo-36048.)
