Java FAQ: How large can a Java BigInteger be?

Answer: The Java BigInteger Scaladoc states the following:

“BigInteger must support values in the range -2^{Integer.MAX_VALUE} (exclusive) to +2^{Integer.MAX_VALUE} (exclusive) and may support values outside of that range.”

The Scala BigInt wraps Java’s BigInteger, so it will also have the same data range.
