[New-bugs-announce] [issue15136] Decimal accepting Fraction

[Jon Clements]

New submission from Jon Clements <joncle at googlemail.com>:

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?
