I think FF = 1 Byte = 8 Bits AND FFFFFFFFFFFFFFFF = 8 Bytes = 64 Bits 18446744073709551615 = 2^64
However to account for negative numbers, 1 bit is used to determine if the number is positive or negative. So, if I'm correct, the upper limit would be 2^64 or ~ 9.22337 * 10^18 (I can't calculate the number exactly). If you determine the exact value of 2^63, you should be able to store this number, but 2^63 + 1 should not be able to be stored.
