How to know what previous flags compose a final flag?

[nicolasg]

Hi. I'm working with item flags for first time, I know this flag (134217758) was made with this previous flags sum:

1 << 1;    // 2

1 << 2;    // 4

1 << 3;    // 8

1 << 4;    // 16

1 << 27; // 134217728

Sum of all results = 134217758

Now, how i can revert the final flag (134217758) to get 27, 4, 3, 2 and 1?

I know that in C# it can be done with the following code

for (int index = 0; index < 64; ++index)
ClbItemFlag.SetItemChecked(index, (flag & 1L << index) > 0L);

But I want to do it in lua and I don't understand exactly how this code works... Obviously This: "(flag & 1L << index) >" 0L Is returning a boolean, but I don't understand why it returns a bool...

P.S: And yes, if anyone asks, I don't know exactly what I'm doing...
