Hello, If no one has any objections to the current exception usage in commons-numbers, I suggest we close NUMBERS-40. This would allow us to continue with the beta release (as mentioned in another thread).

Below is a summary of the public exception types explicitly thrown by each module. arrays IndexOutOfBoundsException IllegalArgumentException combinatorics IllegalArgumentException NoSuchElementException UnsupportedOperationException complex NumberFormatException IllegalArgumentException complex-streams IllegalArgumentException core ArithmeticException IllegalArgumentException fraction ArithmeticException IllegalArgumentException gamma IllegalArgumentException primes IllegalArgumentException quaternion NumberFormatException IllegalArgumentException IllegalStateException rootfinder IllegalArgumentException Nothing in this list strikes me as being inconsistent. The types are all standard JDK exception types and seem to be used appropriately, IMO. Is there any work that needs to be done on this issue? Regards, Matt J
