Get the lower 32 bits of the long
Get the upper 32 bits of the long
Create a long out of 2 ints such that the first int is the upper 32 bits of the long and the second int is the lower 32 bits of the long.
Create a long out of 2 ints such that the first int is the upper 32 bits of the long and the second int is the lower 32 bits of the long.
[a - upper 32 bits][b - lower 32 bits]
Split a long into 2 ints (the reverse of makeLong())
