Description

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.
