What's this structure called?

I know this kind of structure is used in programming a lot:

Code:

0 = None
1 = Warrior
2 = Cleric
4 = Paladin
8 = Ranger
16 = Shadow Knight
32 = Druid
64 = Monk
128 = Bard
256 = Rogue
512 = Shaman
1024 = Necromancer
2048 = Wizard
4096 = Magician
8192 = Enchanter
16384 = Beastlord
32768 = Berserker
65535 = Any/All

...and I want to write some code that will convert the number into a list of classes. Should be easy to Google right, but I don't know what keywords to use--I don't know what these kinds of structures are called. Anyone know?

And if you're willing to save me a step and you happen to know, anyone have an algorithm that would produce a list from the number? Or know where to look for one?
