Answer 1

decimal.DivisionUndefined is raised when you attempt to divide zero by zero. It's a bit confusing as you get a different exception when only the divisor is zero (decimal.DivisionByZero)

>>> import decimal.Decimal as D
>>> D(0) / D(0)
Traceback (most recent call last):
  File "<pyshell#1>", line 1, in <module>
    D(0) / D(0)
decimal.InvalidOperation: [<class 'decimal.DivisionUndefined'>]
>>> D(1) / D(0)
Traceback (most recent call last):
  File "<pyshell#2>", line 1, in <module>
    D(1) / D(0)
decimal.DivisionByZero: [<class 'decimal.DivisionByZero'>]
