New submission from Szymon <szymon1...@gmail.com>:
str(Decimal("0.00000001")) always returns "1E-8" and there is no way to
directly get the "0.00000001" string back without writting custom method for
converting DecimalTuple to string. This is caused by arbitrary choice of `and
leftdigits > -6` condition in
https://github.com/python/cpython/blob/master/Lib/_pydecimal.py#L1052 .
The hardcoded value of -6 should be parametrizable. This can be done by adding
it as argument to the __str__ method or maybe by adding it to the decimal
context.
