Thundre commented on MATH-744:
------------------------------
I noticed that floatValue() has the same bug. Stand by for more patches.
> BigFraction.doubleValue() returns Double.NaN for large numerators or
> denominators

> Key: MATH-744
> URL: https://issues.apache.org/jira/browse/MATH-744
> Project: Commons Math
> Issue Type: Bug
> Affects Versions: 2.2
> Reporter: Thundre
> Attachments: site.patch, test.patch
>
>
> The current implementation of doubleValue() divides numerator.doubleValue() /
> denominator.doubleValue(). BigInteger.doubleValue() fails for any number
> greater than Double.MAX_VALUE. So if the user has 308-digit numerator or
> denominator, the resulting quotient fails, even in cases where the result
> would be well inside Double's range.
> I have a patch to fix it, if I can figure out how to attach it here I will.
