factorial function should change #10

Open GoogleCodeExporter opened 8 years ago

GoogleCodeExporter commented 8 years ago 
factorial must change to ==>

public static BigDecimal factorial(long x) {
        BigDecimal result = BigDecimal.valueOf(1);
        for (long i = 2; i <= x; i++) {
            result=result.multiply(BigDecimal.valueOf(i));
        }
        return result;
    }

becos is x is big enough,result will bigger than Long.maxVal()
