Long is a synonym for System.Int64

ULong is a synonym for System.UInt64

Thes are both binary, or base-2, representations of numbers where each bit
represents binary digit. The difference is that for signed types the bit
which would otherwise store the most-significant digit is instead used to
store the sign, with 0 for positive and 1 for negative.

signed numbers have one bit that represents pos or neg values..
