Examples of org.apache.commons.math3.exception.MathArithmeticException

org.apache.commons.math3.exception.MathArithmeticException
Base class for arithmetic exceptions. It is used for all the exceptions that have the semantics of the standard {@link ArithmeticException}, but must also provide a localized message. @since 3.0

                for (int j = 1; j <= k; ++j) {
                    sign = -sign;
                    sum += sign * binomialCoefficient(k, j) * ArithmeticUtils.pow(j, n);
                    if (sum < 0) {
                        // there was an overflow somewhere
                        throw new MathArithmeticException(LocalizedFormats.ARGUMENT_OUTSIDE_DOMAIN,
                                                          n, 0, stirlingS2.length - 1);
                    }
