In Java, most of the primitive types are signed (one bit is used to represent the +/-), and therefore when I am exceed the limits of this type, I can get many strange things, like negative numbers.

In the BigInteger class, I have no limits and there are some helpful functions there but it is pretty depressing to convert your beautiful code to work with the BigInteger class, specially when primitive operators don't work there and you must use functions from this class.

I was wondering if you had this problem, and if you have any better solution than the BigInteger class?

Thank you.
