      Description

        These thresholds need to be set to values appropriate for the set of targeted platforms:

            private static final int KARATSUBA_THRESHOLD = 50;
            private static final int TOOM_COOK_THRESHOLD = 75;
            private static final int KARATSUBA_SQUARE_THRESHOLD = 90;
            private static final int TOOM_COOK_SQUARE_THRESHOLD = 140;
            static final int BURNIKEL_ZIEGLER_THRESHOLD = 50;
            private static final int SCHOENHAGE_BASE_CONVERSION_THRESHOLD = 8;
