Long is an integer format that uses 32 bit for data. The highest bit is the sign, so the variable ranges from -2^31 (-2147483648) to 2^31-1 (2147483647).
However, in Oblivion, all longs are actually stored as floats, so they experience the same limitations as floats, and so cannot actually reach the ranges that a long should be able to reach (see the float article for more information on float's limitations; see the Discussion here for information on how this was discovered).
If a Global long is declared, it will actually behave as a float, and so will not round off decimal values like it should. In other situations, it will round off.
