New submission from Adelson Luiz de Lima :

When I round this: round(Decimal('9.925'), 2), in Python 3.7.5 the result is 
Decimal('9.92'), but in Python 2.7.17 is 9.93

[issue39124] round Decimal error

Adelson Luiz de Lima  added the comment:

Thanks for the quick response. 
I try the follow code in python 3.7: 
round(9.925, 2) => 9.93
round(Decimal('9.925'), 2) => Decimal('9.92')

I do not understande why behavior of float is diferrent of the Decimal.

In python 2.7 I have the same result: 9.93
