Andrew Brampton updated MATH-1083:
----------------------------------
Description:
The Fraction constructor rejects a denominator of zero. However, while trying
to parse some Strings generated by another program, I encountered a fraction
"0/0". I would say that's ambiguous as to if that's valid, but some people
would agree the answer is zero.
So, would it be possible to allow a zero denominator if the numerator is also
zero. I'd be happy to provide a patch.
