> Current Fraction class uses BigInteger due to the fact that in extreme cases adding and subtraction of fractions can require 65 bits of precision. However this is very costly in terms of performance for all but the most extreme cases. This ticket proposes using long-based arithmetic for Fraction addition and subtraction, and recommending BigFraction if the operation may run very large.
