Hi Marcus and thanks for the acknowledgement.
Here's one more suggestion for your code.
Your current implementation of fact() for calculating factorials has nothing to
offer that isn't provided by math.factorial. Since this is all about Decimal
calculations, shouldn't you modify it to something like:
def fact(x):
""" fact(x) factorial {x} int x > 0
(x must be integral)
"""
return +Decimal(math.factorial(x))
to make it return a Decimal rounded to context precision?
