I'm not a numeric expert but I was looking at a post on S/O which related to converting a Fraction to a certain amount of decimal places. I've had a hunt on the tracker but couldn't find anything relevant, but if I've missed it, I apologise. # F=Fraction, D=Decimal classes If I try num = D( F(5, 7) ) I get: TypeError: Cannot convert Fraction(5, 7) to Decimal So I do: >>> D(f.numerator) / D(f.denominator) Decimal('0.7142857142857142857142857143') Which I think is the correct result? I guess my question is - should Decimal do this implicitly for Fraction?

# F=Fraction, D=Decimal classes
If I try num = D( F(5, 7) )
I get: TypeError: Cannot convert Fraction(5, 7) to Decimal
So I do:
>>> D(f.numerator) / D(f.denominator)
Decimal('0.7142857142857142857142857143')
Which I think is the correct result?
I guess my question is - should Decimal do this implicitly for Fraction?
